It’s been another good month for Pan-species listing, with a surprisingly high 180 new additions to my list. My overall total is now 3933, with 1204 additions this calendar year, and 1513 new species since I compiled my list last August! I’m now not quite sure what my end of year target should be, but I hope to reach an overall total of at least 4000.
That’s the overview, so here are the usual facts, figures and photos from across the groups!
Fungi: At last a notable increase in my total for this group! 30 new species, bringing me up to 161 for the group. I’ve made a proper start on rusts and mildews. Though not the most glamorous of fungi, they’re often host plant specific, so I find them far easier to ID than most ‘macro’ fungi.
Bryophytes: It’s been a while since I’ve found anything new in this group, but the bryophyte season is now underway again. 2 new species added taking my group total to 199. The floating liverwort Riccia fluitans, and a hornwort- Anthoceros agrestis. Both quite localised species.
Vascular plants: A healthy 30 additions to my list, taking my total to 955 for the group. Ahead of my end of year target of 950. I wonder if I can manage to reach four figures by the end of the year… probably not! Mostly common stuff added, but a few nice things from a week in Dorset at the beginning of the month.
‘Common stuff’ first. Chenopodium polyspermum, the Many-seeded Goosefoot. Apparently frequent on waste ground, but overlooked by me until recently. Since getting my eye in, I’ve seen it several times!
Arachnids: 6 new species found, my group total increased to 128. A few gall mites, the beautiful spider Arctosa perita, and a new pseudoscorpion- Lamprochernes nodosus, found in abundance by sieving a compost heap.
Orthopteroids: I rarely seem to add species to this list, as I’ve seen most common species. 1 new species takes my group total to 25. Chorthippus vagans, the Heath Grasshopper.
Hemipteroids: 29 new additions taking my group total to 283. A good mix of heteroptera, leafhoppers, delphacids and the occasional psocid.
Left to right: The mirid bug Europiella artemisiae, fairly easily swept from Mugwort (Artemisia vulgaris). The berytid bug (Stiltbug) Gampsocoris punctipes, often abundant on Restharrow (Ononis repens). The lygaeid bug Scolopostethus decoratus, found on heathland at RSPB Arne.
Hymenoptera: 9 new species, bringing me up to 119 for the group. Almost all solitary bees, of which I have no good photos. Megachile ligniseca at Holme Fen was one of the highlights for me.
Coleoptera: The beetle season is very much past its best now, but I still managed 27 new species, taking my group total to 501. Below are a few of my favourites.
Left to right: Protapion ononidis, fairly widespread on Restharrow (Ononis repens) but doesn’t seem very abundant. I had to sweep about 20 plants to find just one! Omphalapion hookerorum, another Apionid, this time associated with Tripleurospermum species of Mayweed. Finally, Mr and Mrs Pseudapion rufirostre, found on Malva spp Mallows. The male has an orange rostrum, so it looks a bit like it has a cold.
Diptera: 11 new species, my group total now 145. Mostly leafminers.
Lepidoptera- Moths: A decent 34 additions to the list, total now 634. Holiday in Dorset at the beginning of the month helped greatly, plus a few leafminers towards the end of the month.
Two of the best from Dorset. Left: Cydia amplana, a scarce migrant. Right: Metalampra italica, a rare recent colonist to Britain, with relatively unknown status
Birds: 1 new species! Hoping for many more in September. White-winged Black Tern at Grafham Water. Distant and mobile, so no photos.
September will have me travelling back to Cornwall, which I hope will benefit all of my lists! The insect season will be drawing to a close, but lichens, bryophytes, fungi, birds and marine life will be going strong, so I hope to keep adding species until university work takes over!
July has been a good month for pan-species listing, with 170 additions to my list across all the groups. This means that I’ve already achieved my end of year goal of 1000 new species! By the end of July, I’d seen 1024 new species in 2017, taking my overall total to 3753. I spent most of the month at home in Cambridgeshire, but the final few days coincided with the beginning of a weeks holiday in Dorset, providing a boost in new species! Here’s the usual breakdown of my new finds during July:
Lichens: 1 new species- Chaenotheca ferruginea. Group total now 21. I’m hoping to push onwards with lichens in a month or two when all the insects and plants disappear.
Fungi: 6 new species, taking my total to 131. All microfungi, including the mildew Erysiphe aquilegiae on my garden Aquilegias.
Vascular Plants: A reasonable 13 new species, bringing my group total up to 925. A few garden escapes from wandering around a local housing estate, including Argentinian Vervain (Verbena bonariensis) and Purple Toadflax (Linaria purpurea). Best of all was Violet Helleborine (Epipactis purpurata) at Monks Wood, and my first ever Sundews! Round-leaved Sundew (Drosera rotundifolia) on Hartland Moor, Dorset.
Arachnids: 10 new species. Mostly spiders including the impressive Raft Spider Dolomedes fimbriatus at RSPB Arne, and Trochosa terricola. Another major highlight was the UK’s largest pseudoscorpion Dendrochernes cyrneus at Woodwalton Fen. A very rare species indeed! Details of its finding are in my previous blog HERE.
Odonata: A rare addition to this list takes my total to 26 (I haven’t been Dragonfly/Damselfly twitching, or North, very much). Keeled Skimmer (Orthetrum coerulescens).
Hemipteroids: A group I’ve been working really hard on this year, and July is a good month for finding them! 58 new species, taking my group total to 254. A terrestrial heteroptera (land bugs) course mid-month helped out, but I’ve also worked hard finding new leafhoppers and Psocids. A selection of some recent finds from Dorset are shown below.
Left: Dicyphus annulatus, a small (3mm) Mirid bug found only on Restharrow. Right: Tuponia brevirostris, another small Mirid, this time found only on Tamarisk. A recent colonist to the UK, first recorded in 2001, this bug is now widespread in southern England.
Hymenoptera: Slightly below par with only 8 new species, taking my group total to 110. Nearly all solitary bees, including the lovely Dasypoda hirtipes.
Coleoptera: 33 new species, so I’m now at 474 for the group. Though a good increase, July has been much harder for finding new beetles, and many weevils and Chrysomelids are past their peak. At the beginning of the month, the moth trap accounted for some really nice species! Here’s a generous helping of my new additions.
Left: Nationally scarce Apionid weevil Squamapion cineraceum. Associated with Self-heal on dry, chalky soils. Right: Curculionid weevil Cathormiocerus spinosus. A brilliantly camouflaged species feeding at the roots of plants on gravelly ground.
Two nationally scarce beetles from the moth trap! Left: Colydiid Aulonium trisulcus, usually found in the feeding galleries of Elm bark beetle larvae. Right: Dytiscid water beetle Rhantus frontalis.
From left to right: Nationally scarce Curculionid weevil Mecinus circulatus. Nationally scarce Chrysomelid Calomicrus circumfusus. Curculionid weevil Rhinoncus castor, associated with Sheep’s Sorrel. Carabid Amara tibialis, distinctive due to its small size (c.5mm) and deep double streaks on each half of the pronotum.
Diptera: 7 new species, bringing my total to 134. I’m certain I should be making more of an effort with flies! My latest addition was the large Tachinid Nowickia ferox.
Lepidoptera- Moths: After an amazing June moth trapping in the garden, new species slowed considerably in July. Luckily, the garden in Dorset was amazing, and gave loads of new stuff over the first two nights. 29 new species, bringing my total to a nice round 600! All of the best new moths came from Dorset, and here are a few of them.
Left: Nationaly scarce A Four-spotted Footman (Lithosia quadra) male. Right: An amazingly fresh example of a Rosy Footman (Miltochrista miniata).
Left: Nationally scarce micro moth Synaphe punctalis. Right: Small Mottled Willow (Spodoptera exigua), a somewhat uncommon immigrant species.
Insects- Remaining small orders: 4 new species, bringing my total to 28. All lacewings, the most recent being Nineta flava shown below.
So with those 170 new species, and my end of year goal of 1000 new species exceeded, where next? Well I’ve decided to try and reach an overall total of 4000 by the end of the year, so I need to find another 247 species! Its amazing to think that I started my pan-species list last August on 2420, and I’m already headed towards 4000. It goes to show the amazing diversity of life that can be discovered.
On Saturday the 15th of July, at about 10:30pm, Brian Eversham and myself headed out to Woodwalton Fen NNR to see if the rare Tansy Beetle (Chrysolina graminis) is nocturnal or not. Our side aim was to find as much else of interest as we possibly could!
We crossed the bridge over the Ramsey Forty-foot Drain to enter the fen, armed with head-torches and sweep-nets. The first thing we came to was a large Oak tree, so we decided to stop and stare at the bark to see what interesting invertebrates were climbing Oak trees at night. We spent some half an hour at the Oak tree, finding bush-crickets, moths, caterpillars, harvestmen, and even the occasional ground beetle. At one point, Brian spotted an odd-looking beetle climbing up the bark. On closer inspection, it was a Psylliodes flea beetle, and then I found something lurking in the cracks behind it: a big pseudoscorpion! It turned out to be Britain’s biggest pseudoscorp (at a whopping 4mm), the Red Data Book species Dendrochernes cyrneus, new to Woodwalton, and perhaps Huntingdonshire! Brian has been kind enough to let me use his photos in this blog, so they’re much better quality than normal!
As we moved onwards up the main ride of the reserve, a Grasshopper Warbler sang distantly. I’m not sure why, but I’d never quite realised that they sing in the middle of the night, so it felt very odd to hear one! Our walk was dominated by moths for a few hundred yards, with Fen Wainscot (Arenostola phragmitidis) by far the most abundant, followed perhaps by Anania perlucidalis. The head-torches also attracted Drinker moths (Euthrix potatoria), which being rather ungainly flyers, were repeatedly battering our faces. Luckily they’re rather soft things, so it’s sort of like being hit with a very small cushion. Here’s a selection of moths- photos by Brian again.
Left to right: Udea lutealis, Argyresthia brockeella, Fen Wainscot (Arenostola phragmitidis) and July Highflyer (Hydriomena furcata).
Other moth highlights included Crescent (Helotropha leucostigma), and a huge abundance of Svensson’s Copper Underwing (Amphipyra berbera) on the famous Rothschild’s Bungalow in the centre of the reserve.
The walls of Rothschild’s Bungalow also gave us roosting Red Admiral (sadly no Purple Emperors), the nationally scarce ant Lasius brunneus, and lots of the spider- Scotophaeus blackwalli (Photo from Brian).
We then headed towards Tansy Beetle area, but couldn’t resist stopping at one of Woodwalton Fens many bridges, which provide areas of bare ground great for finding Carabids (ground beetles) and Lygaeids (ground bugs). Sure enough, I managed one new species for me from each group! The Carabid Platynus assimilis, and the Lygaeid Scolopostethus puberulus. The latter is identified by having the basal two antennal segments uniformly pale, the apical two uniformly dark, and having a rostrum long enough to reach the hind coxae. All features are shown in my phone-microscoped photos below:
Above: The Lygaeid bug Scolopostethus puberulus.
After these many brilliant distractions along the way, we eventually reached the part of the reserve where Tansy Beetles are known to be found. We checked the stands of Water Mint and Gypsywort (known foodplants) very carefully, and found feeding damage, but no beetles! Luckily we found a few other nice beetle species along the way- the bizarre 2mm Pselaphid Rybaxis laminata, and contrastingly, the 2cm Carabid Carabus granulatus! Both new to me. Below is Brians photo of this beasty beetle!
We continued further into the fen, sweeping the Common Reed and Tufted Vetch, which yielded a new Apionid weevil for me- Oxystoma cerdo. It’s a particularly odd looking weevil, with a ‘roman nosed’ look given by the narrowing and bumped rostrum. Phone-microscoped pic of mine below:
We also looked closely at flowerheads that we passed, as these were packed full of moths and beetles. One of our best finds was from the head of Common Ragwort- the chunky Curculionid weevil Brachypera zoilus. Photo by Brian.
Before heading back, we switched off the head-torches to appreciate the sounds around us, and listen for more Grasshopper Warblers. Unfortunately we didn’t hear any Warblers, but just listening to the wind gently blowing the reeds, whilst looking up at the Milkyway (a rare sight in Cambridgeshire!) was lovely.
So, my thoughts after my first ever nocturnal fieldwork session… brilliant! Compared to fieldwork in the daytime, it seemed much more productive (unless you prefer bees, wasps and most fly families). Each sweep net seems more full, with more interesting things, and the tree trunks come alive! I can’t wait for the next time.
I can hardly believe it’s been so long since I last blogged- 2 months! Unfortunately the reason behind this is that I’ve been really quite unwell, for much of this time. I’ve found that getting out and amongst nature when I can, even for just half an hour has helped me to stay positive.
Much of May was spent down in Cornwall at uni. It was a month of exams, but I managed to get out from time to time to some great places, and found lots of cool things! June has mostly been spent at home, trying to get back to work, and visiting local wildlife trust reserves. At the beginning of May, my pan-species list stood at 3229. By the end of June I’d managed to get to 3583, an increase of 354, leaving me only 146 species from my goal of 1000 new species this year! Here’s how the species were added across the groups:
Fungi: 7 new species added, mostly gall causers, taking my total to 125.
Vascular Plants: 23 new species, bringing my group total to 912. Here’s a collection of some of the more memorable species, mostly from the Lizard!
Arachnids: 19 new species, taking my total from 93 to 112. A real mixture of species- a few gall mites, some spiders, and a harvestman: Odiellus spinosus.
Hemipteroids: As insect season really got underway, I managed to find lots of new species in this group: 65 to be precise! My group total by the end of June was 196. I’ve managed a few new leafhoppers, and several new psocids, including two uncommon species living on the walls of my house: Blaste quadrimaculata and Loensia variegata. Most of my new species were Heteroptera (true bugs), which are beginning to become one of my favourite groups. Here are a few of my favourites:
Hymenoptera: An increase of 15 species from 87 to 102. Most of these new additions were bees (which I’m slowly learning), but I also managed two new ants, a group which I’ve been looking at for 5 years! Myrmecina graminicola and Temnothorax albipennis, within a few feet of each other on the Lizard. Despite my love for ants, I must concede that my favourite new hymenopteran was a bee: Eucera longicornis! (Hand credit Will Hawkes).
Coleoptera: This is the group I’ve made by far the most progress with. I’ve been starting to learn weevils (from all families) and seed and leaf beetles (Chrysomelids) this year, as well as having a go at identifying almost any beetle I can find! All of this effort resulted in 114 new species during May and June, taking my total to 441. It’s really hard to choose which species to include in this blog, but here’s a few of the weirdest, coolest and best!
First up, a few weevils. From left to right: Coelositona cambricus, an odd looking weevil that looks to me to have the texture of old carpet! Cionus scrophulariae, the commonest ‘Figwort weevil’. Dryocoetes villosus, debatably not really a weevil, but the ‘Bark beetles’ have now been placed in the family Curculionidae. Finally, Nanophyes marmoratus, one of Britains’ two Nanophyid weevils. This pretty little species is found on Purple Loosestrife.
Now, some of the weirder species! Left to right: Tillus elongatus, from the family Cleridae. Glaphyra umbellatarum, a nationally scarce A Longhorn beetle found at Monks Wood. Anobium fulvicorne, now in the family Ptinidae. The pronotum almost completely covers the head. Last but not least, another Ptinid: Ptilinus pectinicornis, with its amazing pectinate antennae! The whole beetle is only 3mm long.
These three beetles at first seem unrelated, but they have one thing in common- they all turned up in my garden moth trap! First, the Carabid (Ground beetle) Stenolophus mixtus. Second, Trox scaber! A cool, rough looking beetle, usually found in birds nests. Finally, the best on the bunch, nationally notable B weevil Phytobius leucogaster. Usually found feeding on Water-milfoils!
Finally, two beetles from Fen Drayton Lakes. Left: the tiny ladybird Scymnus frontalis. One of the smaller Coccinellids, which some people might not recognise as a ladybird at all! Right: the fairly scarce Carabid (ground beetle) Microlestes minutulus. This species was discovered new to Britain in 1995, and is spreading through South-east England.
Diptera: Never my best group, but I managed to add 22 species in May and June, taking my total to 127. I added a few nice new hoverflies, including Xanthogramma citrofasciatum on the Lizard, and a few new leaf miners, including Phytomyza leucanthemi. I found this species on a cultivated Daisy species in my garden, and managed this cool picture showing the internal frass by holding a torch behind the mine. Thanks to Barry Warrington for helping confirm the ID.
Lepidoptera- butterflies: 1 new species! As I’ve seen most common butterflies, and don’t go out of my way to find more species, this is a rare addition! Small Pearl-bordered Fritillary from the Lizard.
Lepidoptera- moths: It’s been an excellent two months for moth trapping, both in Cornwall, and back home in Cambridgeshire. The hot spell in June produced some of the best garden moth trapping I’ve ever had, with countless new species, and a Huntingdonshire (VC31) first macro moth- Cloaked Pug (Eupithecia abietaria). In total, 73 new species takes my total to 571.
A couple of new moths found by day. Left: Red-necked Footman (Atolmis rubricollis) found at Monks Wood. Right: Burnet Companion (Euclidia glyphica) feeding on Agrimony.
Insects- remaining small orders: 9 new species, taking my total to 24. A couple of Mayflies, and several Lacewings- a group I’m becoming more fond of.
Fish: 1 new species, and it’s my biggest fish yet… Basking Shark! Seen off the Lizard on a beautifully warm day in May. Missed out on Ocean Sunfish twice in the same day. My group total now 52.
Birds: 5 new species, all from Cornwall of course, and all in May. My group total is now 264. The five were: Richard’s Pipit, Purple Heron, Red-rumped Swallow, Iberian Chiffchaf and Bee-eater! I must thank Toby Phelps for allowing me to hop in his car for endless birding and short-range twitching (and long range dipping, in the case of Portlands Spectacled Warbler).
Richard’s Pipit phonescope record shots, from fields on the edge of Lizard village.
A rather trickier bird to photograph, but some decent record shots from Toby. Red-rumped Swallow at RSPB Marazion Marsh.
Looking back through May and June, I can hardly believe it myself how much stuff I’ve seen! With only 146 more species to go for 1000 new this year, will July be the month I make it?!
It’s been a busy few weeks, mostly spent doing fieldwork, working, identifying stuff and moving back down to uni, so I’ve been neglecting my blog a little bit. So to make up for it, here’s a big colourful blog about all the new things I managed to find during March and April, on my way to 1000 new species this year.
In total, I managed 131 new species during the month of March!
Algae: 10 new species this month, all seaweeds (marine macro-algae), taking my total to 40 for the group.
Lichens: A poor 3 more species added, taking my total to 20. I’ve decided to leave these until the autumn.
Fungi: Slowly increasing as ever, 2 new species. Total 110 for the group.
Bryophytes: As the main bryology season drew to a close, I managed 19 new species, taking my group total to 197. Amongst these species were some excellent liverworts: the extremely rare Riccia crystallina, and the highly localised Sphaerocarpos michelii. Thanks to Matt Stribley for telling me where to find them.
Vascular Plants: I managed 13 new species, taking my total to 884. These included the grass Poa compressa, and a couple of classic Cornish escaped Campanula species. Also Ranunculus tripartitus, the very localised Three-lobed Crowfoot, found on the Lizard.
Cnidarians: An increase of 2, making a total of 12. One of these was an awesome stalked jellyfish: Haliclystus octoradiatus. I can’t remember what the other was!
Molluscs: 9 new species, so I’m now at 110 for the group. Additions included a monstrous 20cm Sea Hare: Aplysia punctata!
Bryozoans: An increase of 1, from 3 to 4. Cellepora pumicosa.
Annelids: 4 new species, taking my total to 17. A few of the easier rockpool species.
Arachnids: 3 new species, bringing me up to 79 for the group. The highlight by far was the Spitting Spider: Scytodes thoracica, found and brilliantly photographed by Will Hawkes.
Myriapods: An increase of 1, taking my total to 51.
Crustaceans: A surprising increase of 11 species, bringing my total to 45 for the group. I’m very pleased with my additions to this group, which included 5 isopods from the genus Idotea, and some cool crabs, including this purpley Risso’s Crab: Xantho pilipes.
Orthopteroids: 1 addition, an Unarmed Stick-insect found by Ellie Mayhew! Temporarily brought indoors for people to come and admire. A real Cornish speciality, naturalised since 1979!
Hemipteroids: 9 new species, including a few Psocids (I’m not sure why these are part of hemipteroids in PSL groupings, surely they should be in ‘remaining insect orders’?). Total now 86.
Hymenoptera: 10 new species bringing my total to 77. Mostly solitary bees, added with guidance from Will Hawkes!
Coleoptera: Perhaps my favourite insect group currently. 15 new species this month, increasing my total to 235. Mostly weevils, including ‘species 3000’ Neliocarus nebulosus.
Diptera: 4 species added, up to 93 now overall. These included the hoverfly Cheilosia albipila, seemingly not recorded in Cornwall for a couple of decades!
Moths: 4 new species, now at 487. These included the wonderful Pine Beauty (Panolis flammea).
Echinoderms: 1 new species, the green sea urchin (which isn’t always green) Psammechinus miliaris. Total now 7 for the group.
Fish: After being relatively stuck for new fish for quite a while, 5 new species was excellent! Total now 51 for the group. Additions included Shore Rockling (Gaidropsaurus mediterraneus, right), Butterfish (Pholis gunnellus, top left) and the rare Giant Goby (Gobius cobitis, bottom left).
Birds: 3 new species this month, and all pretty nice things if I don’t say so myself! Hume’s Warbler (twitched on Portland with Toby Phelps and Liam Langley), Bonaparte’s Gull (a super showy individual half an hour from campus) and a Hoopoe (quick diversion from birding on the Lizard to see it)! Now at 257.
Mammals: 1 new species this month, total now 39. I was persuaded to add Human (Homo sapiens) to my list by fellow PSLers.
April has been the biggest month so far with regards to adding new species to my list. I surpassed my own expectations by quite a way, with 204 new species! 6.8 new species per day on average. This did include an epic 40+ lifer day involving a day out in chalk grassland (Devil’s Dyke, Cambs) and the Brecklands with Brian Eversham, followed by about 7 hours of microscope IDing!
Fungi: 8 new additions, mostly gall-causers. Total now 118.
Vascular Plants: 5 new additions taking my total to 889. One new species was the long awaited Pasqueflower, at Devil’s Dyke, Cambridgeshire.
Molluscs: 3 new species, total now 113.
Arachnids: 14 new species. A mixture of gall-causing mites and spiders. A personal highlight was finding the fairly localised spider Steatoda phalerata on the Suffolk coast.
Hemipteroids: A fairly substantial increase of 45 species, from 86 to 131! This included lots of species of Leafhopper (Cicadellidae), a few Planthoppers (Delphacidae), a Lacehopper (Cixiidae), and lots of Heteroptera (Bugs). Far left: A common leafhopper species, Eupteryx florida. Mid left: A common lacehopper species, Tachycixius pilosus. Mid right: A planthopper species associated with Sand Sedge (Carex arenaria), Kelisia sabulicola. Far right: A lacebug (family Tingidae), Physatocheila dumetorum. Fairly frequent on lichen covered trees, but at 2.5mm long, easy to miss!
Hymenoptera: 10 more species, bringing my total up to 87. These were all species of solitary bee, and included Nomada goodeniana.
Coleoptera: Beetles were very much a focal point for me this month. I specifically targeted the various weevil families (Curculionidae, Apionidae, Rhynchitidae etc.), and the seed and leaf beetles (Chrysomelidae), but also spent lots of time attempting random beetles that I came across. I managed 92 new species, bringing my group total to 327! Here are some pictures to illustrate the amazing diversity of beetles, a sample of things new to me in April!
Curculionid weevils left to right: Phyllobius viridearis, Acalyptus carpini, Curculio glandium, Mogulones asperifoliarum. P.viridearis was my last lifer in April, and 500th lifer for the year.
Orthocerous weevils left to right: Exapion fuscirostre, Apion frumentarium (Apionidae), Neocoenorrhinus pauxillus, Tatianaerhynchites aequatus (Rhynchitidae).
Chrysomelid beetles left to right: Cassida vibex, Longitarsus dorsalis, Bruchus rufimanus, Phyllotreta vittula.
Other beetles left to right: Salpingus planirostris (Salpingidae), Psilothrix viridicoeruleus (Dasytidae), Aderus populneus (Aderidae), Glischrochilus hortensis (Nitidulidae).
Diptera: 12 new species, meaning that I’ve finally reached 3 figures for the group! 105 now the total. Most additions were leaf miners, gall causers, and Bibionid flies.
Moths: 11 new species, my total is now 498. A few leaf miners, and a few common-ish species that I’ve finally caught up with, such as Common Heath, Ematurga atomaria.
Insects remaining small orders: 1 new species. I actually had 3 new lacewings, but realised that my two thrips species belomged in the ‘hemipteroids’ category.
Birds: 2 new species, bringing my total up to 259. Contrasting with the rare and scarce additions during March, these were both long-term bogey species: Black Tern (at RSPB Minsmere) and Common Crossbill (seen whilst dipping the Haddon Hill Two-barred Crossbill). Crossbill is probably the best finch I’ve ever seen.
Other animals: 1 addition, so my total is at last 1! The gall causing nematode worm Ditylenchus dipsaci, easily found on Ribwort Plantain (Plantago lanceolata).
I’ve been doing lots of fieldwork recently, and have seen loads of cool stuff, so its been hard to choose a species to write about! I’ve been getting started on learning my bees this year, using Stephen Falks brilliant bee guide. So this weeks species is a bee, Gooden’s Nomad Bee: Nomada goodeniana.
Many people are surprised by the diversity of bees in Britain, we have nearly 275 species! One of these species is the Honeybee (Apis mellifera), roughly 25 are Bumblebees (Bombus spp.), and all of the other species are solitary bees. Of those solitary bees, 34 are in the genus Nomada, which are all roughly wasp-like in appearance, and cleptoparasitic on Andrena mining bee species.
Nomada goodeniana is cleptoparasitic on the common Andrena species A.nigroaenea and A.nitida, as well as the much scarcer A.thoracica. The female Nomada finds the nest hole of one of its host species, and sneaks in whilst the adult is absent. They lay one egg in the wall of a nest cavity, containing a grub of the host with its food store. The Nomada larva then eats the host Andrena larva, and all of its food store!
Recognising a Nomad bee isn’t too tricky, but identifying it to species can be. First you need to figure out if its male or female. Males are slightly slimmer, with slightly longer 13 segmented antennae. Females are stockier with shorter, 12 segmented antennae. Males are then identified by having no red or brown marks on the abdomen, 0 or 2 yellow spots on the propodeum (never 1 large spot), an unbroken yellow band on tergite 2 and mostly orange hind tibiae. All of these features can be seen in the photos above and below. Females are recognised similarly by having only yellow and black abdomens, 2 yellow dots on the propodeum and a complete yellow band on tergite 2.
Nomada goodeniana is frequent throughout southern Britain, becoming scarcer and more localised further North (a pattern seen in many bee species due to their thermophilic tendencies). Here’s its distribution map (may not be complete due to the NBN atlas not having all datasets yet):
Yet another two week gap since my last blog. I don’t like leaving it so long, but exams had to come first. I’m now home for a month, and although working, will try to blog more often! The species I’ve chosen this week is extra special to me, as it was the 3000th species (of anything and everything) that I’d seen in the UK. I found it for the first time last sunday. The weevil Neliocarus nebulosus.
With its portly figure and plodding movements, I find it to be a rather friendly looking little weevil. Its identification isn’t ever so easy, but the features include: 3-4mm long, keeled elytral base, eyes asymmetrically curved to give a swept-back appearance and pronotum widest at or behind the middle.
This weevil is typically found on low growing plants, often near the roots, where it presumably feeds on the roots and/or foliage (I can’t find any specific information on its diet!). It is most frequent on light and sandy soils in fairly open habitats, such as heathland, or coastal grassland. I found my individual by beating Gorse bushes on a Cornish clifftop.
Neliocarus nebulosus is quite widespread in England and Wales, becoming rarer further North. It is almost absent from Scotland. It seems odd that a seemingly generalist beetle is quite rarely recorded. Though widespread, records are thin on the ground. The excellent new NBN atlas (replacing the NBN gateway) shows this well: https://species.nbnatlas.org/species/NHMSYS0020152778#overview
