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.

Tiny pink and cream colored cube under 2mm stuck to the surface of a leaf. There were several, scattered around randomly, but the photo is cropped to show the one that was in best focus. The second picture shows a bit of my thumbnail in the corner, with sparkly nail polish. Tiny pink and cream colored cube under 2mm stuck to the surface of a leaf.

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

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.

A giant colonial spiderweb in a sulfuric cave on the border between Greece and Albania may be the largest ever found — and it was built by spiders we didn't know liked the company of others.

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

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!

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

A rather ghoulish #Arachtober post for the end of October - a fungus infested Liny found this week.
A tiny spider engulfed in white fungal threads with numerous thin white 'fruit bodies' erupting from its body. The spider's brown legs are visible as are its dark, shiny chelicerae. The spider is sitting on a piece of dark wood.
