Apologies to all users of our new online Atlas for the current intermittent access issues. Our hosts at CEH are working hard to resolve them.

Was incredibly excited to find a female wolf spider in the back garden with babies on her back!

After she gave me a front display she turned round and gave me chance to do a higher magnification stack of all the babies

@3DMert Attulus pubescens, though this is a rather light coloured individual. The species is commonly found in / around houses

[BAS @BritishSpiders]

@Racine1634 Hmm, do Flower Crab spiders generally turn yellow if on a red flower?

[David Metcalfe @Racine1634]

@BritishSpiders nature red in tooth and claw (but sometimes also yellow)

Star find (although there’s been many) of the day today Heather Crab Spider here in Southern Bulgaria on a @Greenwings Wildlife Tour :)

[BAS @BritishSpiders]

@IreneBoston2 Most likely a Pardosa species

Lovely to photograph these yesterday in the garden. @BritishSpiders

Zebra Spider (Salticus scenicus) with an unfortunate Garden Grass-Veneer (Chrysoteuchia culmella).

Photographed in my Grandfather’s garden in Dorset this morning. @BritishSpiders @BritishMoths

Cucumber Spider (Araniella sp.) from the Kelvin Walkway, Glasgow.

This tight portrait was shot on the OM SYSTEM OM-1 Mark II with the M.Zuiko 90mm Macro and CygnusTech diffuser setup. Stacked in Helicon Focus & Lightroom.

f/8, ISO 200, differential,flash 1/64 power.

[Weemadbeasties @davidha60766557]

This walnut orb-weaver sat long enough for a single shot before disappearing back into the undergrowth. No focus stacking, no tricks—just one frame captured on the OM System OM-1 Mark II with the 90mm Macro and CygnusTech diffuser, then processed in Lightroom.

A surprise find on deadwood @WorcsWT Brotheridge Green yesterday afternoon beautiful ground spider Trachyzelotes pedestris. Most records SE of Severn-Wash line 🕷️💚🍃

[Oliver C Wright @OW_Photography]

I managed to find another wolf spider with babies today :) She gave me a side view and then a back view before she went deeper into the foliage.

IMHO one of the most interesting views in UK nature!

Handheld stacked shots with Canon R5ii and RF 100mm f/2.8 L macro

I got as far as wolf spider with this one... assuming that's right?! Any ID help appreciated. At Strumpshaw Fen in the ditches. @BritishSpiders

[BAS @BritishSpiders]

@IreneBoston2 You are correct, it is a female wolf spider (Lycosidae). It is one of the Pardosa species but not possible to get to species without microscopy

[Jez Martin @jeztmartin]

@BritishSpiders I sent a photo last week of possible Pirata piscatorius, but not good photo. Today better photo, good for this species ? From heath pond in Dorset

[BAS @BritishSpiders]

@jeztmartin That has quite a pale-coloured carapace with pale Y & also appears to have a pale cardiac mark on abdomen and very obvious white lateral bands. It’s definitely not Pirata piscatorius and likely P. piraticus but cannot eliminate the other Pirata / Piratula species

@OW_Photography @BritishSpiders @BASSurveys It blew our minds when we photographed this in our garden at the weekend. I bet my husband the spider's fuzzy back was full of babies, and I was right! So many legs!! 🤩 Have since seen many more 'Mumma Spiderling Rafts' 🥰

[Oliver C Wright @OW_Photography]

Saw one of my favourite macro subjects today; female wolf spider with babies on her back

Was in a terrible place to photograph but did manage to get this before she went deeper into the undergrowth

You can see the split in the large egg sac she made so the babies could emerge

A sub-adult male Nuctenea umbratica, Walnut Orb Weaver, wandering in the garden last night.
