How did you submit the record? iRecord? If so, I think you can edit the record altho’ I haven’t tried.

Ero aphana (sternum checked) - female on the underside of the lid of our green bin when I put it out just now. Always a good place to check. Only my 2nd in & around the garden.

@cofnod.org.uk will undoubtedly have a few suggestions. My contribution is Kryptonesticus eremita. Currently only known in the UK from a disused mine entrance on Flat Holm island and a Penarth sewer chamber.

There should be matures by May. It's not the easiest genus for reliable visual ID, but there's always help at hand!

Sticking with spiders for this one. Here's a female Walnut Orbweaver (Nuctenea umbratica) I found a couple of nights back. They have a slightly flattened abdomen allowing them to hide in cracks and crevices during the day.

Yes, definitely a Pirata although I'd be bit cautious on species at this time of year, when they're immature.

Due to various circumstances I have not had any trips out looking for spiders so far this year! Fortunately I have been looking after some spiders that have kept my interest. Not had anything to personally post so decided to share some pictures of local spiders from previous years.

A spider I don't see nearly as often as I should - the delightful Green Meshweaver (Nigma walckenaeri). This one was found trapezing after dark, and even when she sat down I needed some comically acrobatic manouevres to get the shot (hence the suboptimal sharpness).

Thank you! It's always hard for us, working as a team on Bsky, to remember who does and who we still need to persuade!

A little spider fest this morning on these building site fence panels. I think these are Pisaura mirabilis, Xysticus cristatus and maybe one of the Lycosidae? #arachnids @britishspiders.bsky.social

Amazing how a little warmth brings out the sunbathers! Agree on the IDs although perhaps wouldn't go beyond genus for the Xysticus, especially at this time of year when it's still immature.

Steatoda nobilis photos and info Steatoda nobilis photos and info

Mmm, the abdomen looks as if it could be an extremely pale Zygiella Missing-sector orberb spider but the carapace looks oddly uniform in colour for that. Another possibility could be a very pale Steatoda nobilis Noble False Widow - a bit like this one eurospiders.com/Steatoda_nobilis.htm

A nice little Oak Jumping Spider, Ballus chalybeius, from the New Forest yesterday, not an Oak in sight but she didn't seem worried, spring must be on the way!

Great photos - great #spider -thank you! If you're not already doing it, please do record via irecord.org.uk/enter-srs-records

Beyond it looking like, as you say, a lovely guy, I'm afraid we're struggling to identify it from this image. Do you have any others we can look at?

More great images, thank you, Wayne. I think you record your #spiders, but, just in case not, please do add them to the Spider Recording Scheme via irecord.org.uk/enter-srs-spiders.

This Cyclosa conica spider (Trashline Orbweaver) was trying to blend in on a small tree. I've only ever seen this species once before, then found two on this one trip. The other stayed in its web for the second shot.

Sorry we missed this news when it came put, Wayne. Many congratulations! It's such a great image - as well as a gift of a colour-coordinated #spider.

Although we focus mostly on GB species, this North American gallery is a real treat for everyone who appreciates form, function and beauty in #spiders, as well as great #macro.

A great surprise earlier this week - one of my photos gained a second place in the annual Close Up Photographer of the Year @cupoty.bsky.social awards 😃. An unexpected result amongst some amazing photographers. www.cupoty.com to see the stunning finalists and winners.

The localised wolf spider Alopecosa barbipes - or Easter Fox-spider - at Margam Mine yesterday. A rather typical species of coal spoil sites in South Wales.
