Summary of 2018 wildlife recording

Here we go with my 5th annual summary of my ongoing quest to experience, understand and enjoy the biodiversity of Britain. Previous summaries can be found at these links for 2014, 2015, 2016 and 2017.

2018 was another busy year, and in total, I recorded 2,302 species in Britain, my highest ever tally. In part, I achieved this simply by keeping better track of which species I really ought to be seeing (based on a summary of what I’d seen in the past) so I didn’t simply forget to write things down. Additionally, we didn't do much foreign travel in 2018, apart from a short trip to Spain in February and a few days in Rome in August. Finally, this was the year that I finally bit the bullet and tried to become more of a "proper" entomologist by actually pinning specimens for future reference (mostly Hymenoptera and Diptera), which again enabled somewhat better coverage. As ever though, the more deeply you look at wildlife, the more it's apparent that you're just scratching the surface and there remain many groups that I pay very little attention to at all.

Mapping out my records (I love mapping with QGIS!) I see I travelled a little more widely in 2018 compared to last year. I have only just realised though that I failed to make it to Scotland or Wales this year. My East Anglian recording "footprint" was very similar to 2017, again mostly around Thetford, Shotesham and the Yare Valley. Not a single visit to Titchwell or Minsmere! One New Year's resolution is to try to visit inland mid-north-west Norfolk next year, which is hugely under-recorded for lots of groups.

A whistle-stop tour of the year: The start of 2018 was really dominated by the harsh weather in late Feb / early March ("the beast from the east") and it really was pretty extreme, with us unable to leave the village for about five days. The first decent day of PSL'ing was a trip to Flordon Common in March with Steve Lane, Tim Hodge and Martin Collier where I notched up a dozen new species, mostly beetles. At the start of April we had a week's family holiday in west Cornwall, one of my favourite places. I focused on rock-pooling as this is something I've done very little of, and coastal critters formed the bulk of my 39 new species here. From April onwards I started catching sawflies at every opportunity as I'd taken on the role of county recorder for this under-recorded group. In May, I spent an excellent few days in Shropshire for the NFBR annual conference and field trip; the latter, to Brown Moss, netted me 18 new species and it was particularly helpful to spend time with other experienced naturalists, notably caddisfly guru Ian Wallace. Highlights of June were an organised moth-trap event at Catfield Fen and an afternoon in the Brecks, both with John Martin. In July I helped with Chris Packham's national bioblitz week by recording at both Lakenheath Fen and Weeting Heath, and I also had a good long walk one morning around Cranberry Rough, Stowbedon Common and Thompson Common - a really good area that I need to return to more often. In August we spent a few days up in Teesdale, trying to focus on the many botanical specialities of the area but it was really a bit late (especially as the summer was particularly hot) and consequently quite difficult/frustrating. I also had an excellent few days with Mark Lawlor in Surrey, Kent, Essex and Norfolk mid-month. In September I had my biggest single-day tick-tally with 26 new species on a Wild Flower Society outing to Coalhouse Fort (not just plants either). We then returned to the inner Thames at the end of the month to make a pilgrimage to see the extraordinary Beluga off Gravesend (the first time Trudy has ever talked me into twitching something!) I spent much of the early autumn chasing down insects in a quest to reach 5,000 species and then, having done so, I took it easy for the last few months of the year to recharge the batteries.

During the year I made 5,555 biological records comprising 2,302 species. Of these, 444 were new for me and brought my total to 5,036 species in Britain. This exceeded my expectations for the year and reinforced the feeling that it still isn't that hard to find a lot of new species if you just look carefully. I thought I would have to attend some fungus forays in the autumn to reach the target but in the event I didn't have time as the insects didn't stop. I don't really have a good feel for how 2019 will pan out, but reaching 5,500 would be nice to aim for. I do intend to continue the focus on Hymenoptera though, which are particularly species-rich (if sometimes difficult!)

Many thanks to everyone who helped me during the year, either in the field or online - and not forgetting the unsung heroes of wildlife recording: the compilers of keys, many of which are freely available online. Big thanks also, as always, to my ever- (well, usually-) patient family.

Species per year

Records per year

Non-arthropod invertebrates

Worms (1 species, 1 new, list total = 13)

I didn't put any effort into looking at worms this year, except for finding this kelp strand on the beach at Marazion covered in the shells of Spirorbis inornatus, some of which were still occupied by the worms.

Spirorbis inornatus, Marazion

Bryozoans (1 species, 1 new, list total = 1)

This is a substantial group of about 300 aquatic species; I'd previously only seen the remains of Flustra foliacea (Hornwrack) along beaches but never ticked it. However, I found a colony of Membranipora membranacea on a kelp strand at Marazion beach which, under the microscope, did appear to have a little more life about it. Hard to be sure really, but good enough.

Cnidarians (4 species, 3 new, list total = 5)

We found four species of sea-anemones in the rock-pools in Cornwall, three of which were new to me: Actinia fragacea (Strawberry Anemone), Anemonia viridis (Snakelocks Anemone) and Aulactinia verrucosa (Gem Anemone).

Anemonia viridis (Snakelocks Anemone), Cape Cornwall

Echinoderms (4 species, 4 new, list total = 4)

We identified two starfish and two brittlestars from the Cornish rock-pools. I've previously only seen dead starfish washed up on the beach, so these were great.

Asterina gibbosa (Cushion Star), Cape Cornwall

Molluscs (10 species, 4 new, list total = 60)

Most of those identified were rock-pool species in Cornwall, including the splendidly colourful Gibbula umbilicalis. I was also shown two new freshwater snails in Shropshire (Galba truncatula and Omphiscola glabra), and Mark and I stumbled into the enormous Helix pomatia (Roman Snail) in Surrey. Still not a group I get excited about though generally (I see I didn't get round to identifying a single slug this year).

Gibbula umbicalis

Helix pomatia (Roman Snail)

Tunicates (1 species, 1 new, list total = 1)

An entirely new group to me, I found this strange thing in a rock-pool at Cape Cornwall which completely stumped me. Other kind folk helped me name it as Botryllus schlosseri (Star Ascidian). Despite its jelly-like appearance, this is more closely related to the vertebrates than to other invertebrates.

Botryllus schlosseri (Star Ascidian)

Non-insect arthropods

Arachnids (44 species, 20 new, list total = 118)

A mixed year. I mostly ignored harvestmen (no new ones) and added just a couple of new gall-mites. I had a few short bursts of spider-enthusiasm, but am still not really making sufficient headway with this important group. However, it was nice to clinch three of the big beasts: Dolomedes fimbriatus at Thursley Common, Segestria florentina at Sheerness docks and Steatoda nobilis (Noble False Widow) inside a school in Norwich (for the latter, I declined to notify the staff for fear of propagating the continuing ridiculous panic). I had a new pseudoscorpion, Lamprochernes chyzeri, brought to me by a colleague accidentally as she'd potted a fly in her office for me to identify and it was attached to the fly's leg! The fly also proved to be a rare one. Finally, one of the highlights of the year was Mark and I making a night-time pilgrimage to Sheerness docks to see the long-established population of Euscorpius flavicaudis (Yellow-tailed Scorpions), helped enormously by the loan of a colleague's UV torch. Highly recommended!

Euscorpis flavicaudis (Yellow-tailed Scorpion), Sheerness

Sea-spiders (1 species, 1 new, list total = 1)

One of the species I was most pleased to encounter this year was my first ever sea-spider, an obscure group that are distantly related to the other arachnids. We'd crashed an organised rock-pooling event at Marazion and someone else found a sea-spider; it would have been left unidentified to species but I deftly snuck it away and was later able to name it as Nymphon gracile.

Nymphon gracile, Marazion

Crustaceans (24 species, 10 new, list total = 34)

A good haul of these in 2018, mostly whilst rock-pooling (in addition to the usual common woodlouse species). I managed to sort out four new crabs and three new barnacles, as well as Palaemon serratus (Common Prawn) at Marazion and the tiny but colourful marine isopod Eurydice pulchra in sandy pools at Sennen beach.

Eurydice pulchra, Sennen

Myriapods (9 species, 0 new, list total = 34)

I didn't pay too much attention to myriapods this year, just noting a few common species early in the year.

Springtails, proturans and 2-tailed bristetails (6 species, 5 new, list total = 10)

I'm still somewhat nervous of tackling springtails, which is silly really as often when I try to identify one it keys out reasonably easily. I did tackle a few at the start of the year, and readily doubled my list (although there are about 400 to find). Particularly pleasing was Anurida maritima on the surface of rock-pools at Porthcurno.


Insects

Ephemeroptera (Mayflies) (2 species, 0 new, list total = 7)

Not a group I paid much attention to this year.

Odonata (Dragonflies) (26 species, 1 new, list total = 37)

A reasonable selection this year, with a notable spread of Norfolk Hawker to Shotesham this year, plus further Willow Emerald sightings around the village. Mark and I dipped on Southern Migrant Hawkers in Essex (a little too late I think). I also dipped on Vagrant Emperor on a cold day at Kessingland, but in this case I was well chuffed to find my own Red-veined Darter. This is something I've been avoiding twitching for years in the expectation I'd eventually bump into one - nice when it finally happens!

Sympetrum fonscolombii (Red-veined Darter), Kessingland

Dermaptera (Earwigs) (1 species, 0 new, list total = 3)

Just Forficula auricularia (Common Earwig) as usual.

Orthoptera (Grasshoppers and crickets) (15 species, 1 new, list total = 22)

I came across most of the expected species during the year (no Common Groundhopper though) and it was good to belatedly identify only my second Woodland Grasshopper from photos taken by Mark at Queendown Warren. Best of all though, in November I found my first Southern Oak Bush-cricket on the roof of the car at home, after just driving back from Diss. This is still a rare insect in Norfolk, although clearly on the increase.

Meconema meridionale (Southern Oak Bush-cricket), Shotesham

Plecoptera (Stoneflies) (1 species, 0 new, list total = 8)

Just one common species noted.

Hemiptera (Bugs) (143 species, 41 new, list total = 244)

I wasn't really intending to focus on bugs particularly this year, but I do like them and by the end of the year I'd seen far more species than in previous years, including 41 new ones. They're quite a good group to look at towards the tail-end of summer when some other groups are waning a little. It's a shame they're still relatively little appreciated by many naturalists, as lots are really quite distinctive. Some of my favourite new ones this year included Capsodes gothicus, Pithanus maerkelii, Prokelisia marginata, Syromastus rhombeus, Gargara genistae and both species of Stictopleuron (which were common in the Brecks and must be increasing as I can't believe I haven't seen them before). Oddly, I didn't see Tritomegas bicolor (Pied Shield-bug) at all this year, despite it usually being a very readily noticed species. Does anyone know anything at all about population dynamics in these I wonder??

Neottiglossa pusilla (Small Grass Shieldbug), Thetford Forest

Psocoptera (Barkflies) (5 species, 1 new, list total = 12)

I was fairly lazy with psocids this year, but did manage to find the (relatively) huge Psococerastis gibbosa along the riverbank in Thetford in July.

Coleoptera (Beetles) (174 species, 43 new, list total = 555)

I stepped back from beetles somewhat this year in order to focus more on Hymenoptera (there's only so much time available and you can't do everything). This was the lowest number of species I'd recorded for four years, and there were several common species I never got round to keying to confirm, such as Cantharis rustica, Pterostichus niger, etc. However, I certainly haven't given up with beetles yet and did find a few nice things. One of the best was the first Norfolk record of Glaphyra umbellatarum (Pear Shortwing Beetle) netted in Thetford in June, whilst I was also pleased with finding Demetrias imperialis from Claxton Marshes, Trachys subglaber at Flordon, Pyrochroa coccinea at Preston Montford, Mogulones geographicus at Cranwich Camp, Aromia moschata (Musk Beetle) in Thetford and Myrrha octodecimguttata (18-spot Ladybird) from Thursley Common.

Glaphyra umbellatarum (Pear Shortwing Beetle), Nunnery Lakes

Diptera (Flies) (165 species, 51 new, list total = 415)

I wasn't planning to focus much on flies this year, and indeed didn't pay sufficient attention to confirm a number of very common hoverflies (such as Syrphus ribesii, Melanostoma scalare, etc). However, as the sawflies declined by mid-summer, I did end up collecting a fair number of flies of which almost a third proved to be new species for me. Most of these are apparently common species, but some nice finds included Conops vesicularis, Dioctria baumhaueri, Lipoptena cervi, Chrysopilus asiliformis and the apparently rare Chrysopilus laetus all around Thetford.

Chrysopilus laetus, Thetford (with attached pseudoscorpion, see earlier)

Volucella inflata, Howe

Hymenoptera (sawflies, wasps, bees, ants) (246 species, 122 new, list total = 348)

Symphyta

I tried to make sawflies a real focus of the year, given that I'd taken on the role of county recorder, and given that they are really poorly known. As a result, I tried to catch every sawfly I possibly could and ended the year with 331 sawfly records. It was a late spring and I didn't find any until 14th April with two species (both new) on Shotesham Common. Records peaked in May and June but dropped sharply from July, so these really are a group to focus on from the start of summer. Overall I managed to identify 104 sawfly species of which 62 were new for me. Many of these were species that have seldom (if ever) been recorded in Norfolk previously, given the low level of recording of the group. Some particularly nice finds included the tiny Xyela julii, my first two Pamphilus species, Pachnematus calcicola (new for county), Macrophya alboannulata (technically new for county, post-split), Phylloecus xanthostoma, Arge ciliaris, Fenusa altenhoferi (mines, new for county), Allantus rufocinctus (new for county) and Fenella nigrita (mines, new for county). Finally, the event of the year was the appearance of the rapidly colonising Aproceros leucopoda (Zigzag Elm Sawfly), first recorded in the UK in 2017 but by the end of 2018 clearly present very widely indeed (pretty much every patch of elm in Shotesham). I will be continuing to investigate sawflies closely in 2019, hopefully trying to get records from some less well-recorded parts of the county.

Aproceros leucopoda (Zigzag Elm Sawfly), Shotesham

Tenthredo mesomela, Shotesham

Parasitica

The Parasitica comprise the majority of the Hymenoptera, about 6,500/7,700 British species. I find them fascinating but they really are the great unexplored continent of biodiversity, and can be highly daunting. However, there were some great new books published in 2018 which, coupled with me making a start with making a reference collection of pinned specimens, meant that I did make a little bit of progress. I identified 36 species during the year of which 23 were new, mostly involving larger ichneumon wasps, but I was pleased to find my first species in the family Proctotrupidae (Proctotrupes brachypterus at Claxton). It was also good to rear two species of Polemochartus (braconids) from the 'cigar' galls in reeds created by Lipara flies. The ichneumon species Apechthis compunctor gets a special mention as being species number 5,000 on my list. I intend to continue to look more closely at Parasitica in 2019.

Apechthis compunctor, Rockland Marshes

Aculeata

Another interesting year for aculeates, with 106 species identified. I mostly looked at them later in the season when the sawflies started declining. Amongst the new species were 16 bees (four each of Colletes and Lasioglossum and a range of others), three of the stunning jewel wasps, 14 crabronid wasps (still one of my favourite groups), one ant, one spider-hunting wasp and two social wasps. The latter were Vespula rufa (Red Wasp) from Thursley Common and Dolichovespula saxonica (Saxon Wasp) from Croxton Forest.

Nomada marshamella, Shotesham Common

Lepidoptera (Moths and butterflies) (498 species, 24 new, list total = 1125)

Moths

After many years of home-made skinner traps, I finally opened my wallet and shelled out on a Robinson trap for the garden (below), quite extravagent but very nice to use. It only resulted in three new species - Sharp-angled Peacock, Opostega salaciella, Bryotropha terrella - whilst I found two more new moths inside the house - Mompha bradleyi and Achroia grisella, the latter doubtless due to Trudy restocking her bee hives. Other new moths were found out and about in a range of places: I found Elachista albifrontella and Prays ruficeps around Shotesham; Agonopterix purpurea at the Nunnery; long-overdue Festoon in Croxton Forest; Small Ranunculus (larva) and Phalonidia affinitana at Coalhouse Fort. Two organised trap-opening sessions were attended, with Strumpshaw Fen yielding Silky Wainscot and Water Ermine, whilst a spectacular event at Catfield Fen produced vast numbers of Reed Leopard, as well as Ancylis apicella, Cosmopterix lienigiella and Scythropia crataegella. As usual, I also kept an eye out for leaf-miners and during the year added Eriocrania unimaculella (birch), Bucculatrix frangutella (buckthorn, an occupied mine at last after many years of checking), Bucculatrix cidarella (alder), Stigmella atricapitella (oak), Stigmella trimaculella (hybrid poplar) and Stigmella viscerella (elm).

Significant omissions this year were Garden Carpet (again, continued evidence of a crash I haven't really heard anyone else talking about), Double-striped Pug, Purple Bar, Plain Golden Y, Pale Mottled Willow, July Highflyer and Small Phoenix.

Butterflies

Mark and I had great views of our first ever Silver-spotted Skippers at Queendown Warren in Kent (after dipping at Box Hill the previous evening). Other nice butterflies this year included Adonis Blue, Chalkhill Blue and White-letter Hairstreak, whilst particularly noteworthy was the arrival of Silver-washed Fritillary in Shotesham. I didn't record Grayling or Green Hairstreak in 2018.

New moth trap, Shotesham

Phragmataecia castaneae (Reed Leopard), Catfield Fen

Hesperia comma (Silver-spotted Skipper), Queendown Warren

Mecoptera (Scorpionflies) (1 species, 0 new, list total = 2)

I failed to find Snow Flea on a hunt around Roydon Common in February. I should get out in the Brecks now, come to think of it....

Neuroptera (Lacewings) (2 species, 1 new, list total = 14)

Little attention paid to these; I don't find them particularly memorable, and get a bit bored keying yet again what usually turn out to be the same species. However, Chrysopa perla from Catfield Fen proved to be a new one.

Trichoptera (Caddisflies) (29 species, 11 new, list total = 44)

Another reasonable selection this year, with the new species coming from the garden moth-trap, the riverbank in Thetford and outings to Catfield Fen and Brown Moss (where it was great to have Ian Wallace helping).


Vertebrates

Fish (8 species, 5 new, list total = 15)

Not a bad year for fish, by my very meagre standards. Rock-pooling in Cornwall produced my first records of Lipophrys pholis (Shanny), Coryphoblennius galerita (Montagu's Blenny) and Nerophis lumbriciformis (Worm Pipefish). Additionally, two very common species were added: Scardinius erythrophthalmus (Rudd) from Strumpshaw and Muck Fleet, and Cottus gobio (Bullhead) from Teesdale. I'm never going to be a world-class angler...

Lipophrys pholis (Shanny), Porthgwarra

Amphibians (4 species, 1 new, list total = 7)

As well as the three common species, the highlight was tracking down Pool Frog at a semi-secret site in the Brecks with John.

Pelophylax lessonae (Pool Frog), Brecks

Reptiles (3 species, 0 new, list total = 6)

After one of the hottest summers on record, Mark and I tried to find Sand Lizard on the Surrey heathlands on the first subsequent rainy day, with predictable lack of success. Best sighting was nearly stepping on an Adder at Thetford Warren in September.

Birds (182 species, 2 new, list total = 434)

Birding was again fairly low-key this year. The two new species weren't brilliant - the American Bittern in Suffolk could have been, but I only had very brief flight view, whereas the Stejneger's Stonechat at Salthouse was OK, but I don't really follow the ID niceties sufficiently to have really appreciated it. Plenty of other nice things though, with some other highlights being increasing numbers of Great White Egrets, a distant King Eider, a nice (no, really) Caspian Gull, Black-winged Stilt, etc. As usual in recent years, without actually making an effort with birds it's easy to miss some common species, the most notable gaps in 2018 being Guillemot, Razorbill, Bewick's Swan, Eider, Common Scoter, Greenshank, etc.

Fieldfare in the garden during the heavy snows

Larus cachinnans (Caspian Gull), Sheringham

Mammals (20 species, 1 new, list total = 42)

The majority of the mammals seen were unexceptional, although included four encounters with Otters (Santon Downham and Shotesham) which are always fun. However, the undoubted highlight was the very lost Beluga in the Thames at Gravesend in September, particularly notable as being the first time Trudy has talked me into twitching something. We had good views (well, it was mostly underwater of course) for an extended period from Gravesend sea-front, along with ice-creams - very civilised. The main mammal gap this year was Porpoise, which I guess I'm less likely to see these days as I do little sea-watching.

Delphinapterus leucas (Beluga), Gravesend

Plants

Algae (9 species, 1 new, list total = 18)

I managed to name nine species from Cornish rock-pools, with only Sargassum muticum (Wireweed) new to me. There were clearly dozens more species present, but I think I really need to learn these alongside an expert to progress much further.

Sargassum muticum (Wireweed), Penzance

Bryophytes (21 species, 5 new, list total = 70)

I made a few attempts with these during the year, but they just don't really float my boat to be honest. I've only got so much attention span and they don't measure up to insects for me. So the new species were OK, but not exciting. Except - Goblin Gold! What a cool thing this is, glowing in the dark of caves, we saw it in an ancient stone tunnel at Carn Euny in west Cornwall, thanks to gen from Calum Urquhart's blog. So there is one bryophyte I like!

Schistostega pennata (Goblin's Gold), Carn Euny

Vascular Plants (599 species, 67 new, list total = 1047)

I notched up quite a tally of plants in 2018, partly through making sure I wasn't forgetting to write down obvious ones, but also by taking advantage of experts like John Martin and Alex Prendergast, and attending a Wild Flower Society event at Coalhouse Fort. I also made efforts to hunt down some of the Teesdale specialities, with fairly limited success, plus made a few targeted visits for certain key species. All this helped push me over the 1,000 mark at last. Some of my favourite new plants species included Marsh Cinquefoil, Holly-leaved Naiad (at Hickling from the Weaver's Way without having to get a boat or go swimming), 8 new umbellifers including Hog's Fennel and Sickle-leaved Hare's-ear, Sea Daffodil, Greater Bladderwort, Toothwort and Shrubby Cinqeufoil. Hoping to get up Ben Lawers in 2019, so lots more to come...

Peucedanum officinale (Hog's Fennel), Hamford Water

Holly-leaved Naiad, Hickling Broad


Fungi etc.

Fungi other than lichens (34 species, 12 new, list total = 204)

I largely ignored fungi in 2018, except from a few very obvious species and a selection of plant-specific rusts and mildews. The latter - whilst useful list-fodder - aren't especially exciting things to look at, at least until I get a higher-powered microscope to check them out properly. Potentially the most interesting find was the "rust" spots shown below on Sea Daffodil on Marazion beach. I haven't yet been able to find out which species occurs of Sea Daffodil, but as the plant itself is a fairly new British species, then it's not impossible that this is a new British species of fungus. Hopefully someone more qualified will sort it out in due course.

Unidentified rust on Pancratium maritimum (Sea Daffodil), Marazion

Lichens (8 species, 3 new, list total = 56)

As often seems to be the case, I took quite a lot of photos of lichens but this didn't really translate into sufficient enthusiasm to pursue them more seriously. My excuse is that I'm going to work on them properly when I retire to Cornwall one day! Perhaps the most notable was Pyrenocollema halodytes on barnacles within the Penzance rockpools.

Pyrenocollema halodytes on the barnacle Chthamalus montagui, Penzance

Ramalina siliquosa, Sennen

Slime-moulds (1 species, 1 new, list total = 4)

A delightful clump of Mucilago crustacea (Dog Sick Slime-mould) was found on Shotesham Common in December.

Mucilago crustacea, Shotesham


Overseas

Spain

Duncan and I joined my parents for a few days based at Calpe in February. A little too early for many plants, insects or reptiles, but a nice selection of birds included some very obliging Alpine Accentors, a far-less obliging Moustached Warbler, a huge flock of Glossy Ibis, plus Black Wheatear, Greater Flamingo, Crag Martin, Thekla Lark, Booted Eagle, Penduline Tit and Common Waxbill.

Alpine Accentor, Bernier Ridge

Rome

We spent a few days as a family exploring Rome in August with minimal wildlife watching (I didn't even take my bins). I did manage to find Scarce Swallowtail, Monk Parakeet and Italian Sparrow, and notched up a Vatican City list of seven species.

Look no bins!

Summary of 2017 wildlife recording

Here goes with another write-up of a year's wildlife watching. It's always interesting to look back and pull together many different observations into a single summary, often reminding myself of things I've already half-forgotten about. It's also great to re-read the equivalent summaries I wrote about previous years.

2017 was another species-packed year, although very much a year of two halves. I managed to record 1,820 species in Britain, almost exactly the same as in 2016. For the third year in a row, I recorded over 1,000 species of insects. However, I really lost drive in the second half of the year, probably caused by taking on a new role at work in combination with a post-holiday "low". The "low" was perhaps due to the holiday itself being such a high of course - my first ever trip to Australia (and hopefully not the last), which really was such an amazing experience, it took a while to get back into focusing on the smaller and subtler species of Britain which I've been looking at for the last few years.

Mapping out my records with QGIS, I see I didn't actually travel very much at all within Britain in 2017. Most of the outliers on a 10km map are from a few work trips and a few days back home in Yorkshire, but the vast majority of my time was spent in East Anglia.



Even more striking, I didn't really go many places in East Anglia; the 1km scale map below shows that almost all my recording was in my home area south of Norwich and around Thetford, with a few excursions to the Broads and the Suffolk coast, and hardly any trips to the north Norfolk coast at all. There seems to have been some sort of invisible forcefield banning me from north of the A11 in fact.


During the year, I found 234 new British species, bringing my end of year total to 4,597, but only 40 of these were post-Australia, meaning I've left myself with quite a mountain to climb if I want to push for 5,000 by the end of 2018. Nevertheless, that's a total which is still quite possible if I put in the effort. Let's see....


Species per year


Non-arthropod invertebrates


Worms (2 species, 2 ticks, list total = 12)
A short session netting the stream in Shotesham in April produced two new leeches: Alboglossiphona heteroclita and Hemiclepsis marginata.

Molluscs (16 species, 2 ticks, list total = 57)
New species were the freshwater Valvata cristata on Shotesham Common in March, and Slipper Limpet Crepidula fornicata on Skegness beach in December (I'd seen shells of this species in the past, but never found occupied ones). A variety of other common slugs and snails were also noted.

Starfish (0 species, 0 ticks, list total = 0)
Still no live starfish found, but a very striking wreck on Skegness beach on 29th Dec involved probably over 1,000 Common Starfish Asterias rubens as well as a couple of Common Sunstars Crossaster papposus. I nudged a fair few, but could find no apparent signs of life.

Starfish buddies on Skegness Beach (sadly both dead)



Non-insect arthropods


Arachnids (38 species, 13 ticks, list total = 97)
A reasonable selection by my standards, although I still haven't got into spiders in a big enough way. The breakdown was 20 spiders (5 new), 4 harvestmen (1 new), 3 pseudoscorpions (1 new) and 11 mites/ticks (6 new). I finally got round to going to Lopham Fen and seeing the legendary Fen Raft Spiders Dolomedes plantarius and also finally caught up with many other naturalists and found myself a Wasp Spider Ariope bruennichi at Minsmere. Another highlight was the pseudoscorpion Lamprochernes savignyi which proved to be abundant in a muck heap in Shotesham, when sieved by visiting coleopterists in May.

Crustaceans (12 species, 3 ticks, list total = 24)
A reasonable selection of woodlice, including my first record of Porcellionides pruinosus which proved to be abundant in a muck heap in Shotesham in May. I was pleased to finally nail Signal Crayfish Pacifastacus leniusculus which I've known have been in the river Little Ouse by work for years. The other new species was the non-native barnacle Austrominius modestus which was encrusting beach groynes at Skegness in December.

Myriapods (15 species, 3 ticks, list total = 34)
A little less attention paid to these this year, but I ought to do more as there's clearly lots still to be found; Melogona scutellaris in the garden was a potential new species for Norfolk. Also in the garden, Geophilus truncorum was new for me, whilst I also sorted out Cylindroiulus britannicus from Thetford.

Springtails, proturans and 2-tailed bristetails (1 species, 1 tick, list total = 5)
I finally got round to identifying the common globular springtail Dicyrtomina saundersi from the garden.


Insects


Mayflies (2 species, 0 ticks, list total = 7)
Ephemera danica recorded several times around Shotesham, with Ephemera vulgata in Thetford.

Dragonflies (20 species, 0 ticks, list total = 36)
First of the year was typically Large Red Damselfly Pyrrhosoma nymphula on the early date of 9th Apr at Whitlingham. Further evidence of a slight range expansion of Norfolk Hawker Aeshna isosceles with records within Shotesham parish on 27th-28th May and 10th Jun, but still not quite into the home 1 km square (2018 surely!) I recorded Willow Emerald Damselfly Chalcolestes viridis in the garden again on 27th Aug (and saw again at Minsmere the following week). Most other common species were noted although unaccountably, I failed to record Common Blue Damselfly Enallagma cyathigerum all year - I presume this was down to incompetence as opposed to a catastrophic population crash.

Earwigs (2 species, 0 ticks, list total = 3)
Pleasing to see Lesser Earwig Labia minor again, after my only previous record in 2000; lots were seen in a muck heap in Shotesham, thanks to the sieving skills of visiting coleopterists!

When I say we sieved a muck-heap....this is home to a squillion invertebrates


Grasshoppers and crickets (11 species, 0 ticks, list total = 21)
Started with my earliest ever nymph of Dark Bush-cricket Pholidoptera griseoaptera in the garden on 15th April. Roesel's Bush-crickets Metrioptera roseselii started "calling" from 1st July in Shotesham (hooray, can still hear them). Otherwise, most regular species noted.

Stoneflies (2 species, 2 ticks, list total = 8)
Both species recorded were new to me, with Nemoura avicularis from Thetford in April being a common species, but Nemoura dubitans from Surlingham and Whitlingham (also in April) much more localised nationally (although it appears that East Anglia is a stronghold).

Bugs (84 species, 19 ticks, list total = 215)
Not a bad selection of bugs, although a little lower than last year. I did pass the 200 mark as hoped for though. Some of the nicest new ones were Gastrodes grossipes at the Nunnery Lakes, Ulopa reticulata in Sherwood Forest, Forget-me-not Shieldbug Sehirus luctuosus in the garden (how have I overlooked this so far, the garden is over-run with forget-me-nots?), Halticus luteicollis in Thetford and the splendid Kalama tricornis also at The Nunnery. Most other common species were noted, although I was lazy and didn't get round to identifying any Psocoptera (barkflies) this year.

Beetles (216 species, 80 ticks, list total = 514)
Although I didn't set out with the intention of particularly focusing on beetles this year, I seem to have seen quite a lot of new ones; in fact, about a third of my new species in 2017 were beetles and I smashed through the 500 barrier. The 80 new species were from 23 different families. I found 23 new rove beetles (Staphylinidae) during the year, including an incredible 11 new ones on 23rd May when Steve Lane, Martin Collier and Tim Hodge came to visit Shotesham; one day, I'll learn to sieve a muck-heap like that! I have learned to look in a variety of places for rove beetles though, finding them under dead pheasants and moles, in henhouse bedding/shit and in sieved flood debris, as well as catching Philonthus cognatus in flight. I suspect the staphs will be my most species-rich beetle family by the end of next year (currently in third place). The next most tick-rich group were the Chrysomelidae with 12 new ones, mostly unremarkable common species although it was interesting to identify the Viburnum Leaf Beetle Pyrrhalta viburni from its larvae feeding on Guelder-rose at Woodbastwick Fen. In third place were the nine new weevils (Curculionidae), a feeble number really given the available targets out there and the fact there's plenty of information on how to find them. I ought to be much more focused on chasing some weevils down in 2018! The ground beetles (Carabidae) remain my most species-rich beetle family (79 species now), although just four additions in 2017: Bembidion illigeri (Barnhamcross Common), Harpalus latus (Winterton Dunes), Acupalpus meridianus and Stenolophus mixtus (both Shotesham). Away from these larger groups, highlights of a hotchpotch of other families included Hylecoetus dermestoides, Nalassus laevioctostriatus and Orchesia undulata (Sherwood Forest), Diaperis boleti at the Nunnery Lakes, the longhorns Phytoecia cylindrica (Nunnery) and Alosterna tabacicolor (Harling Woods), the histerids Atholus bimaculatus (Shotesham) and Saprinus aeneus (under dead mole on Barnhamcross Common) and the large black Prionychus ater (in the garden moth-trap). Lots more to look for in 2018 though - will I make it to 600?

Flies (135 species, 30 ticks, list total = 365)
A good selection, albeit fewer than last year and only half the number of new ones; no excuse as there are still thousands (in fact, almost all of them) still to look for. Nine of the new ones were craneflies, and I still feel like there's lots more easy ones to work out here; four of these were in the garden for example. I saw two new hoverflies (Meliscaeva cinctella at The Nunnery and Eumerus strigatus in Shotesham) bringing my total to 97 species; I clearly need to find some targets for 2018. I also added my 21st soldierfly (Beris geniculatus at Wheatfen), five more of the leaf-mining Agromyzidae, three more of the picture-winged Tephritidae and two more Bibio species (anglicus at Whitlingham and reticulatus at Sherwood bringing my total to 11 out of the 16 species). I also came across two recently colonising non-native species at the Nunnery: the leaf-miner Obolodiplosis robiniae on a False-acacia and Drosophila suzukii in the office. I will be disappointed if I don't make it to 400 flies by the end of 2018.

Hymenoptera (97 species, 35 ticks, list total = 225)
Although I'm clearly remaining very much a pan-species recorder, I've been trying to work out where to specialise a bit more. During the year, a vacancy arose for the position of Norfolk sawfly recorder, and despite not being particularly knowledgeable about the group, I decided to put myself forward - and was accepted! Gulp. Anyway, I do find the Hymenoptera a really interesting group, and there's no shortage of new discoveries to be made, so I will try to focus a little more on these in 2018. But as for 2017:
Symphyta (sawflies): I recorded 33 species during the year, 20 of which were new to me. This brings my total to 65 sawflies, out of a British total of 537. Clearly I need to learn a great deal more to be able to undertake my new role effectively! My new ones included some which are very common and obvious (such as the Alder Sawfly Eriocampa ovata and Figwort Sawfly Tenthredo scrophulariae) as well as others that are a little more obscure. I was pleased to discover the Skullcap Sawfly Athalia scutellariae around a patch of Skullcap in wet woods at the Nunnery Lakes. Another interesting discovery was of some sawfly larvae reported by Mike Dawson on a birch sapling in his garden which proved to be Pristiphora testacea, apparently new to Norfolk. As I said, lots to discover still and I really look forward to getting stuck in this year. Perhaps a target of 100 sawflies by the end of the year is a good aim.
Aculeata (aculeates: bees, ants, some wasps): as well as a new focus on sawflies, I still also really like aculeates. I recorded 54 species during the year, of which ten were new for me. Three new bees were Andrena minutula (High Ash Farm), Heriades truncorum (The Nunnery) and Lasioglossum leucopus (Nunnery Lakes). Five splendid solitary wasps were Argogorytes fargeii, Nysson spinosus and Trypoxylon attenuatum (Shotesham), Astata boops (Barnhamcross) and Ammophila sabulosa (Dunwich Heath). I found the ruby-tailed wasp Chrysis angustula in the garden. Finally, and particularly interesting, I noted the spider-hunting wasp Auplopus carbonarius in Shotesham on 17th June, again on 26th August and finally again in Thetford on 27th October; this species was not known in Norfolk until very recently and is clearly spreading rapidly.
Parasitica (parastic wasps): although by far the most species-rich group, it remains difficult (although not impossible) to break into this group. I recorded five new species, three of which were gall-wasps in the family Cynipidae: Trigonaspis megaptera galls around the base of the Medusa Oak in Sherwood Forest, Biorhiza pallida 'oak-apple' galls in Shotesham (seen many times previously but never confirmed as occupied) and Phanacis hypochoeridis galls on Cat's-ear on Great Yarmouth North Denes. Some additional oak galls were found but the wasps were not actually seen and I don't currently count these towards my totals - Cynips quercusfolii, Andricus curvator, A. lignicola, A. fecundator and A. quercuscalicis. However, one of my favourite finds of the year was the blue wasp Ormyrus nitidulus (Ormyridae) which emerged from galls of A. quercuscalicis that I'd kept. Finally, I only identified one new Ichneumon all year, a female of Virgichneumon monostagon from the garden moth-trap.

Moths and butterflies (423 species, 13 ticks, list total = 1,101)
As ever, Lepidoptera were my most diverse insect group during the year, due to long familiarity and regular moth-trapping (at least once per week for most of the year in the garden). However, due to the number of other things I'm recording, I have got very lazy regarding butterfly recording; I only made 44 records of 24 species during the year, with no new ones again and no records of Grayling, Wall, Dark Green Fritillary, Green Hairstreak, etc. I did record 13 new moths in the year, and for a change, the majority of these were macro-moths. Apart from a splendid Tree-lichen Beauty Cryphia algae at the Nunnery, however, all of the other new macros were pheromone-attracted clearwings. I tried clearwing pheromones years ago and failed, but persevered this year (backed up with better info and, perhaps, better pheromones) I succeeded in recording my first six species, all in June: Hornet (Nun's Bridges), Yellow-legged (Barnhamcross), Currant and Red-tipped (Surlingham Church Marsh), Red-belted (The Nunnery) and Six-belted (Minsmere). All stunning creatures, and I hope to find some of the others in 2018. A few other less regular macro-moths noted in the garden trap included Chamomile Shark, Muslin Footman and The Coronet, whilst significant absences were Shaded Broad-bar, The Lychnis, Rosy Rustic, Lesser Swallow Prominent and Angle Shades; whilst some of these were doubtless not helped by the timing of our trip to Australia, the latter was particularly surprising and was its first blank year following an unbroken run since 1993. The six new micro-moths were Coleophora follicularis (occupied cases on fleabane in the garden), Phyllonorycter cerasicolella (occupied mines on cherry in garden), Ectoedemia argyropeza (occupied mines on Aspen at Fewston Reservoir), Stigmella obliquella (occupied mine on willow in Thetford), Marasmarcha lunaedactyla (Dunwich beach toilets) and Ancylis upupana (Sherwood Forest). Other noteworthy micros included Bucculatrix nigricomella (garden trap), Duponchelia fovealis (inside house on 20th Sep and 14th Oct, my 2nd & 3rd records after finding the 4th for Britain back in 1999), Synaphe punctalis (Dunwich beach toilets), Stathmopoda pedella (Wheatfen) and Pammene regiana (Earlham Park). Conversely, a few suprising omissions were Elophila nymphaeata, Acleris holmiana, Acleris rhombana and Pandemis corylana.

Scorpionflies (1 species, 0 ticks, list total = 2)
Only Panorpa germanica was identified to species this year.

Alderflies (1 species, 0 ticks, list total = 1)
Sialis lutaria was confirmed to species from both Whitlingham and Upton Marshes.

Lacewings (4 species, 0 ticks, list total = 13)
Just four common species were noted: Chrysoperla carnea, Hemerobius lutescens, H. micans and H. humulinus.

Snakeflies (1 species, 0 ticks, list total = 2)
Phaeostigma notata was found dead in a cobweb on the wall of the Nunnery in June.

Fleas (1 species, 1 tick, list total = 5)
Numerous small black fleas were sieved from henhouse bedding in December and looked right for the expected species Ceratophyllus gallinae, although I failed to key them perfectly due to size.

Caddisflies (15 species, 3 ticks, list total = 33)
A reasonable year, with new species being Limnephilus rhombicus from Tasburgh, Leptocerus tineiformis from the garden trap (abundant on a few nights in June) and Oecetis ocharacea also in the garden trap. Of some of the more recognisable species, Limnephilus lunatus was recorded in the garden moth trap between 1st Sep and 4th Nov, Phryganea grandis was noted from Minsmere and the garden moth trap, Anabolia nervosa was noted along riverbanks between 4th and 16th Oct and Chaetopteryx villosa was seen by torchlight after dark on a bridge over the stream in Shotesham on 6th Nov and 22nd Dec. Still feels like I could record much more about these reasonably easily.

Vertebrates


Amphibians (3 species, 0 ticks, list total = 6)
A count of 12 Smooth Newts at a pond by Shotesham Little Wood was notable, alongside a small number of records of Common Frog and Common Toad.

Birds (191 species, 2 ticks, list total = 432)
An unimpressive year-list albeit my highest since 2012. My two new species were on the same day -  Dusky Thrush (Beeley, Derbyshire) and White-billed Diver (R Witham, Lincolnshire) on 29th Jan, both very enjoyable indeed, particularly the diver which I'd wanted to see for years. Other avian highlights of the year included the Great Reed Warbler at the Nunnery Lakes, Parrot Crossbills at Santon Downham, a combination of Iceland, Glaucous, Caspian and Yellow-legged Gulls in Thetford, a great selection of birds around the new Potter Heigham Marshes including Spoonbills, breeding Black-winged Stilts and a Caspian Tern, and finally the autumn influx of Hawfinches, of which I found four individuals/records around Shotesham (including one over the garden). Inevitably with my focus away from birds these days there were many missing common species, notably many seabirds but I also didn't find Spotted Flycatcher, Tree Sparrow, Redstart, Tree Pipit, Raven, Corn Bunting, Common Crossbill, etc etc.

Fish (4 species, 1 tick, list total = 10)
One of my favourite sightings of the year was a Flounder in a shallow tidal pool at Winterton in November (followed by another at Skegness); my first ever live flatfish. The only other species noted were Minnow, Three-spined Stickleback and Perch, the latter my first for the Little Ouse in Thetford. I remain a desperately poor fish-lister!

Flounder at Winterton

Mammals (17 species, 0 ticks, list total = 41)
No new species this year, but nice to see Badger (Menstrie in Scotland) and Otter (Minsmere). The ever-increasing hordes of Grey Seals are making Horsey a bit less of a favoured destination now, given the number of people going to see them (and the fact that they rule out the beach for walking the dog). Chinese Water Deer were recorded in the Shotesham area twice but still not quite into the home 1 km square; surely in 2018? No Weasel or Porpoise this year. Still not come across Pygmy Shrew, Water Shrew and Yellow-necked Mouse - must try harder!

Reptiles (2 species, 0 ticks, list total = 6)
Grass Snakes were regularly counted under felt sheeting at Stubbs Green with a max count of 9 on 2nd April. This species was also seen at the Nunnery Lakes, along with Slow Worm, 10 of which were under sheets on 10th May. Unusually, I didn't come across Common Lizard during the year.

Plants


Bryophytes (7 species, 1 tick, list total = 65)
A completely feeble effort this year with just a handful of common mosses and one liverwort (Lunularia cruciata). The new one was Smaller White-moss Leucobryum juniperoideum in Sherwood Forest in May.

Vascular Plants (448 species, 8 ticks, list total = 983)
At the end of last year I noted I only had 25 more species to find to get to 1,000. Well, I put in a feeble botanical effort in 2017 clearly with only eight new ones. Of these, it was nice to pick up a few native species, including Spiked Water-milfoil at Horsey, Spring Speedwell at Icklingham (my last remaining speedwell in the south), Shepherd's-needle at Mendham and the somewhat embarrassing (but surprisingly difficult in my area) Common Comfrey, finally nailed in Cambridge. The other new ones were non-native: Pale Yellow-eyed Grass at the Thickthorn roundabout (Norwich), Thorn-apple in Shotesham, Soapwort at Minsmere and Peach-leaved Bellflower in Poringland. Having said that, I did spend more time making sure I jotted down the common species I was seeing, so my overall total for the year was much higher than the 295 I noted in 2016. As a result, the omissions from the list were a more genuine reflection of habitats I didn't visit; for example I didn't record Ramsons, Tormentil, Moschatel, etc all of which are present at certain sites locally. Other less regular (for me) species also noted during the year included Grape-hyacinth, White Helleborine, , Slender Thistle, Red-tipped Cudweed, Smooth Cat's-ear, Fringed Water-lily, Yellow Bartsia, Cut-leaved Dead-nettle and Hairy Violet.

Fungi etc.


Fungi/Lichens (49 species, 15 ticks, list total = 245)
I didn't put very much effort into fungi this year, and really should try harder. The new species I recorded were a bit of a mixed bag. Most were micro-fungi on plants, including Protomyces macrosporus (on Cow Parsley), Melampsora populnea (on Dog's Mercury), Puccinia lagenophorae (on Groundsel), Taphrina populina (on Hybrid Black Poplar)Erysiphe heraclei (on Hogweed), Neoerysiphe galeopsidis (on White Dead-nettle), Arthrocladiella mougeotii (on Duke-of-Argyll's Teaplant) and Ramularia centranthi (on Red Valerian). Additional new species were Purple Jellydisc Ascocoryne sarcoides, Crystal Brain Exidia nucleata and Wrinkled Crust Phlebia radiata (all Mousehold Heath), the lichen Peltigera hymenina (High Ash Farm), Phellinus conchatus (Whitlingham Marsh), Hoof Fungus Fomes fomentarius (Sherwood Forest) and Scarlet Waxcap Hygrocybe coccinea (Buckden Pike).

Overseas records


Some great trips abroad in 2017, although short work trips to the Netherlands in January (highlight Short-toed Treecreeper) and Barcelona in November (highlight Monk Parakeets) didn't really get the pulse racing. However, team BUBO had a great few days in Corsica in April where the highlights were obviously Corsican Nuthatch and Corsican Citril, but also Lammergeier and a range of other Mediterranean birds, and a good selection of nice insects and plants; I particularly liked the Early Spider Orchids. A Caspian Tern was a good find too, five minutes from the terminal at Nice airport during a stop-over on the way out.

And then we had an amazing, long-planned family trip to Australia in the summer. What a fantastic place for wildlife watching, and I really want to go back to explore more. I've blogged the hell out of it already, but five months on, the highlights that spring to mind were both some of the special targets - Cassowaries, Golden Bowerbird, Lesser Sooty Owl, Rainbow Pitta, Hooded Parrot, Platypus - but also some of the common species such as the Sulphur-crested Cockatoos. Swimming alongside a Green Turtle on the reef will also take some beating, as will watching the departure of up to half a million fruit bats. But let's see what 2018 has to offer....
