Garden wildlife. A lovely Zoropsis spinimana on the shed last night. Possibly my favourite spider, and one I've seen fairly regularly here over the last few years. And a second one was inside the shed too - only underside views of that one, but they're quite distinctive! @britishspiders.bsky.social

A fairly substantial pale brown spider with quite distinctive darker markings. It's on a garden shed.

I for instar #Arachtober as I don't have any 'I' spiders (maybe @tylanberry.bsky.social @chalkspring.bsky.social etc?) Instar is any stage in the development between moults. The instar immediately before maturity is described as being subadult. Some spiders have a set amount, others are variable.

F for Fun Fact. Floronia bucculenta is the only UK native spider who's scientific name starts with F (I hope!) F is the Feather Legged spiders, Uloborus plumipes (pic) Usually found in garden centres. Uloborus walckenaerius, found only at a few S.Eng sites. #Arachtober @britishspiders.bsky.social

This was a challenge @britishspiders.bsky.social 3 days running, this spider put a main thread on my garden swing cover, which I tried to move... disaster. So I put up a couple of my own string lines and YAY, she used that to secure her web, so now we can both happily sit on the swing again 😍

I was really excited to see some adult Trochosa from the Sphagnum depths of Morden Bog recently - a historic site for the mythical T. spinipalpis. Annoyingly, and unsurprisingly to be honest, all of them were T. terricola, as seems to always be the case from western bogs @britishspiders.bsky.social

Four Araneus species from Lakenheath Fen today. They had very recently mowed the paths and there weren't many spiders to be seen, and NO pyramidatus anywhere, which is usually the spider I see the most. Tetragnatha and Metellina also seen.

Underside of an Araneus. This one is certainly diadematus because of the epigyne.

A grand 4 pseud day yesterday with @jeremybartlett.bsky.social on our little 24 mile cycle ride south of Norwich. Cheiridium museorum was found in the 3 churches we visited while Ephippiochthonius tetrachelatus was found at 1 church. 2 other species found at roadside locations. Details in ALT.

Cheiridum museorum: a tiny reddish-brown pseudoscorpion with a roundish, flattened body and fairly slender claws. It is on a pale piece of wood.

Ephippiochthonius tetrachelatus: a brownish coloured pseudoscorpion with long slender claws that are pale reddish colour. It is sitting facing left on a piece of wood covered in bits of cobweb.

Chthonius ischnocheles: a brownish pseudoscorpion with a dark head, large chelicerae and long, slender pale reddish claws. It is sitting head down on a piece of pale grey concrete. Two of these were found under bits of concrete rubble found at the edge of a roadside woodland.

Chernes cimicoides: a dark, reddish-brown pseudoscorpion with large robust claws on a piece of wood. It has a matt/granular appearance. Its body and pedipalps are covered in short, blunt hairs (called setae). This one was found under the loose bark of a large bough that had fallen from a mature roadside Oak tree.

It's a good time of year to be looking out for the distinctively-shaped Trashline Spider Cyclosa conica. It often embellishes its closely-woven orb web with a line (stabilimentum) of food remains or other debris ('trash'). Widespread, usually in shaded shrubs and trees, across Britain.
