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.

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?

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.

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.

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.
