What appears to be a Helpis sp. Found several spiders varying from spiderlings to approx 4mm in size. Currently rearing two until maturity for definite ID. Readily taking fruit flies. @britishspiders.bsky.social @tylanberry.bsky.social @cofnod.org.uk

Current research, delving into the first monographs on British harvestmen - Meade 1855 and Pickard-Cambridge 1890. Got the pdfs printed and bound together. Lovely plate from Pickard-Cambridge.

Spiders that experience vibrations, visual stimuli, both or none during development do not differ strongly in the size of their brain areas. This is a surprising finding. Even more surprising is that siblings react alike. See our new publication in the J. comp. Neurology. doi.org/10.1002/cne.... 🧪🕷

Ok, i think this one must be Palliduphantes pallidus rather than P.ericaeus? @britishspiders.bsky.social

This is neither here nor there, but I took a couple of wolfies that looked like they might be adult, but with obscured epigynes. Neither was adult, but using the Lycosidae key in Roberts, this wouldn't fit Pardosa. But it looks like Pardosa to me. Is that key not great or need some interpretation?

Walckenaeria unicornis epigyne.

RE-DISCOVERY #1! Our trip to Okefenokee NWR has already resulted in a re-discovery of a long-lost species. Ceratinopsis bona Chamberlin & Ivie, 1944 was last seen in 1943, 82 years ago. In addition to possessing genitalia that match the descriptions, their black tibia IVs are also diagnostic.

If there were contest for smartest-dressed #spider, this dapper Nigma walckenaeri would surely be contender. Hope his good looks proved lucky: he would've had to approach object of his love carefully in her tunnel-like lair to avoid being killed and eaten. In Bungay, Suffolk, at end of last summer.

Robertus lividus. #Arachnids #Spiders #VC55

I truly enjoyed the collaborative nature of making this video, and you might enjoy that mine is not the only face in it. This topic is amazing. youtu.be/_QF6kaOAuYg?...

Very excited for this one - it's going to be all about those super long legs. Why so long? How do they work? How do these arboreal species live? See you then!

This Male Walckenaeria acuminata may be common but its a fantastic looking spider, since getting into Linys this Genus is so fasinating. And its great that the male and female of this species can be Identified with a hand Lens. @britishspiders.bsky.social

From an ancient beech woodland in West Sussex, its a pig to get to with all the gear, and to date ive never seen much there. But thats has changed samples from the 9th November have produced Centromerus cavernarum!!One i had hoped for there. @britishspiders.bsky.social @graemelyons.bsky.social

Diminutive fairy wombat poop. Tiny cubes under 2mm on each side. These are egg sacs made by a spider in the family Theridiosomatidae. They made yesterday’s hike special. Finding something I’ve never seen before is such a thrill. 🌱 #nature #macro #spider

Also from Dersingham wood, leaf litter, Tenuiphantes flavipes and Agyneta rurestris. There were other things. I'd never seen Drapetisca socialis, which we saw a few of, and in the bog, Hypsosinga cf pygmaea and Tibbelus sp, and an odd black and white job under a log (probably a dark Pachygnatha.)

It's sad when huge old trees fall but it does provide opportunities for fossicking around logs and branches and under slabs of bark. And today that produced a new harvestman, Nemastoma bimaculatum. There were also spiders but I've still to go through all my photos.

@britishspiders.bsky.social @tylanberry.bsky.social @cofnod.org.uk Really happy to find this spider (another follow-up of Rowley Snazell's old Bucks records). From a site I'd visited previously, but looking at in a new way, thanks to a tip from @chizz13.bsky.social Walckenaeria dysderoides #spiders

Centromerus serratus, from a site in Sussex. @britishspiders.bsky.social @graemelyons.bsky.social

Garden wildlife. A Zoropsis spinimana on the house wall near the front door last night. @britishspiders.bsky.social #londonwildlife

Nice to see this one, its the first time ive seen the male. From a woodland site in Sussex. Pachygnatha listeri. @britishspiders.bsky.social

My 3rd record for Walckenaeria obtusa at this woodland site, all 3 have been in moss under pines, all my W.nudipalpis records from that site are from leaf litter under sweet chestnut trees. @britishspiders.bsky.social @tylanberry.bsky.social @graemelyons.bsky.social

Well this was neat. World's biggest spiderweb discovered inside 'Sulfur Cave' with 111,000 arachnids living in pitch black | Live Science share.google/IcsbD2Lb3zhT...

I've wanted to see Purseweb Spider since I was a kid, but've never managed to find one despite much searching, so I was overjoyed when one of the other volunteers found this amazing arachnid during this morning's survey work - just look at the size of those chelicerae! @britishspiders.bsky.social

🎉 Celebrating 10 Years of the Colliery Spoil Biodiversity Initiative 🎉 This December marks 10 years since the Colliery Spoil Biodiversity Initiative began its mission to change how people see South Wales’ colliery spoil sites — from barren relics of industry to thriving havens for wildlife. 1/3

What a privilege to have seen both ends of the UK's spider size spectrum - the magnificent Cardinal Spider (Tegenaria parietina) and the diminutive Theonoe minutissima within a few days of each other - a 50x difference in legspan! @britishspiders.bsky.social

@britishspiders.bsky.social @tylanberry.bsky.social @graemelyons.bsky.social Lovely family holiday to Greece (Kos). I managed to find a little time to look for some local arachnids. Amazing diversity in a small place

One that i dont pick up that often, a Nationally Scarce species. Picked up in West Sussex. Monocephalus castaneipes @britishspiders.bsky.social

A nice local story: Rare purseweb spider discovered by visitor at Kinver Edge - www.bbc.co.uk/news/article...

A rather ghoulish #Arachtober post for the end of October - a fungus infested Liny found this week.

Of course, if you want to id spiders you'd best join @britishspiders.bsky.social too! 😁

🧵More on the Coston pseudoscorpions. I collected some corpses from cobwebs in the church to identify at home. On tipping them out, I was amazed & pleased to discover that one was actually alive. Here is Cheiridum museorum, aka the Book Scorpion, now released onto the bookcase to hunt booklice...

Some more Pseudoscorpions from Crates Wood, Shaftesbury. Two Moss Neobisid, Neobisium carcinoides with springtail prey and two photos of a Riddish Two-eyed Chelifer, Roncus lubricus

🎃 Happy Halloween, from the Charnwood Spider! 🕷️ Charnwood Forest is one of the only places in the UK that you can find the spider Mastigusa diversa. Unsurprisingly, it's also known as the Charnwood Spider!

Just in time for #Halloween 👻, a #NewSpecies of trapdoor spider discovered!!! 🕷️ www.ucdavis.edu/climate/news...

A good news spider story from the BBC today www.bbc.co.uk/news/article...

Thanks to those that attended the terrestrial harvestmen webinar! Lovely to speak to you and great questions asked. Tune in for the next one - arboreal harvestmen!

Lichen Running Spider at #RSPBArne today #Spiders @britishspiders.bsky.social

Male Horrid Ground Weaver Nothophantes horridus in Plymouth, Devon. This UK endemic usually peaks in December but I found 16 (mostly adults) one day last week so seems to be having an earlier season this year.

I took these photos of a Green Elf Cup Fungi (Chlorociboria aeruginascens), it was only when putting them on the PC. I noticed this tiny Chthonius ischnocheles, the first I've ever seen around 1.5-2.5mm 😬 #Chthoniusischnocheles #falsescorpion #invertebrates #arachnid #macro

What I think is a juv. C.atropos. Was looking for them in an area I have found them before but no larger spiders. Have inc a C.a previously found nearby. #Aractober @britishspiders.bsky.social
