I’m thinking this may be Anelosimus vittatus (Banded Comb-footed Spider)?What do we think @britishspiders.bsky.social?

It’s possible altho’ wouldn’t want to say it definitely is based on these photos. The silhouette of the palp looks right for Anelosimus vittatus rather than similar Kochiura aurica, though (see arachno.piwigo.com/index?/categ...)

Suspect this is a female Philodromus dispar ... crab spider on Cow Parsley @britishspiders.bsky.social

No, don’t think so Gary. It’s definitely a running crab spider, Philodromus species and one of the aureolus group but not dispar. It’s a sub-adult male too judging by those palps.

A Trochosa species. If this was in UK, would most likely be Trochosa ruricola but may be other similar species in NL.

It seems the two spiders are a Fencepost Jumping Spider, Marpissa muscosa & Heliophanus cupreus. Hopefully correct ID’s @britishspiders.bsky.social

Stuart, no arguments with your ID of Marpissa muscosa ✅ but not sure we can ID the Heliophanus to species with certainty. It’s definitely a female Heliophanus but could be cupreus or flavipes.

A large jumping spider, brown with black stripes. Thickened front legs suggests male. I didn’t check.

The number of times I’ve checked this old gate post for spiders! And it’s finally paid dividends with Marpissa muscosa. On the Ouse Cut Off Channel.

A scared spider hunched up in a green plastic flower container. Her abdomen is very swollen suggesting she is full of eggs.

Look who I disturbed while tidying the garden! She looks frightened. Sorry! Looks like she’s ready to pop. I put her somewhere nice and safe.

Any suggestions? Best photo I have with this 2mm liny'. Simply not clear enough for me to ID. Woodland habitat, reddish legs. Hopefully someone can recognise the mantis shape. If not will keep for it for when I have better scope. Ta

Thank you, Vanna. We have a great team running the recording schemes and we're also indebted to the fantastic staff at brc.ac.uk for their programming skills, turning records into an Atlas. The new Atlas' forerunner, our widely acclaimed SRS website, also set high standards! @kitenet.bsky.social

This looks like a fantastic resource, well done to everyone involved in setting it up, and also for linking it so that it will continuously update!

ObsIdentify says Neriene montana of the Liniphyiidae.
Is that okay?

A spider conundrum & not very clear photos to help solve it. Found this on bedroom wall last night, next to an open window so not necessarily a house spider. I live next to a slice of ancient woodland, sth Wales coast (ST17). So, could this be Tegenaria silvestris? @britishspiders.bsky.social

Half an hour turning over logs this afternoon in a very small local wood found 12 Harvestmen of the species Rilaena triangularis, this is my highest count so far this year for this species in this tiny wood. #Harvestmen #Arachnids

I'm so sorry, Jan! The False-widow possibility is very interesting. Our Eratigena expert says he's also seen them in this odd posture but not known the reason. This is another one of your fascinating observations that deserves further exploration.

Odd that they're such a reliable bath species - suspect them of dropping in from the roof via a skylight window. Is that a possibility with yours?

I think Andrew is right - it's quite a variable species although not commonly recorded along the S Wales coast. Please do record via the Spider Recording cheme iRecord form to contribute to the map: irecord.org.uk/enter-srs-records

That would be brilliant!

Mmm, not sure, Ruth. It's a sub-adult male and immature Araniellas are notoriously difficult - and often quite orange. I'm copying in @cofnod.org.uk for a more informed view!

BAS recording schemes record entry form | iRecord Enter the recorder's name, if different. More than one recorder can be entered in this field.

Much appreciated if you can record it via the spider-harvestman-pseudoscorpion Recording Schemes dedicated form on iRecord:

A tiny pinkish Pseudoscorpion is seen in one of the lettering indentations on the surface of a brick. The Pseudoscorpion is facing toward upper left of picture, and its 'claws' are stretched out in front.

A beautiful Common Chthonid seen in the garden. A few upturned bricks are kept in tucked away places as pseudoscorpions can often be found there.
