From the same location as yesterday. Two very much most likely Drassodes sp (Haplodrassus look similar) Varying from a pale toffee to a more velvety mahogany colour, doesn't really show in the pictures #Aractober The median eyes help separate them from the Clubiona

Something else found on willows at Whitlingham today was this Marbled Orb-weaver, Araneus marmoreus var. pyramidatus (srs.britishspiders.org.uk/portal.php/p...). Very noticeable against green leaves, but you can see how it might blend in once the leaves start to yellow in autumn.

A spider with a round yellow abdomen with a brown area near the back. The legs are banded dark brown and white. It is resting on the underside of some willow leaves, with a yellowed willow leaf to the left of the picture.

#Aractober Woodlouse spider, Dysdera crocata. An adult male. Not great palp shots. Has femora spines, garden find plus at 11mm it's not going to be D erythrina. For more ID tips visit srs.britishspiders.org.uk/portal.php/p...

Metellina have a tuning fork marking on the carapace. Think it's Floronia bucculenta, chameleon spider. Not seen one before @britishspiders.bsky.social will know. Great picture

Not sure if it is

Shame you didn't find any this time. Your right about the photo, Eratigena. Not possible to decide which one without microscope work.

Platnickina tincta. Mostly juv. this time of year. Easy to find amongst ivy in my area. Have used an older photo of a more mature one as they are tiny atm. #Aractober

Wacky unicornis - two from Sundays efforts in the Wicken fens. I can't spell Walckenaeria. Or can I?

#arachtober A-Z:

Day 6 - F for Floronia - the chameleon spider
Day 7 - G for Gnaphosa (the best spider genus in the best spider family, no other opinions accepted)
Day 8 - H for Heteropoda - giant huntsman spiders (pictured is the delightful H. davidbowie)

Will try and get a look under the microscope over the weekend. Ta

Definitely the smallest sub/adult non money spider I've yet found. Almost passed it by but the spinnerets caught my attention. Need someone to confirm ID pls @britishspiders.bsky.social Hahnia sp. Possibly H.nava as long hairs on the abdomen? New for me. #Aractober @tylanberry.bsky.social

Mark Telfer and I only went and refound Aulonia albimana on the Isle of Wight two days ago! Quite possibly the best spider find of my life! Lots of other records too. analternativenaturalhistoryofsussex.blogspot.com/2025/10/whit...

I'm still shook by this, it's like 5 mice taking down a lion, but the lion can fly 😳

Yellow jacket next to a crevice in a wooden post, out of which a pseudoscorpion is grabbing the antennae of the wasp to hold it down

Wider view, with another pseudoscorpion poking out of the crevice to grab at the yellow jacket's stinger basically??

Closer shot of the the previous pseudoscorpion whose latched onto the yellow jacket's posterior, and a pale small baby pseudoscorpion is getting in on the action

A pseudoscorpion for #arachtober. A Compost Chernes [pselaphochernes scorpioides] from the garden compost heap.
#wildlifefrommywindow #invertebrates #ukwildlife #gardenwildlife #macro

A plan view of a eight legged invertebrate that has two long arms reaching out from its head with crab like claws on the end. The body looks like one large reddy brown oval, with the main portion bisected by a lighter line, with each side split into 10 regular sections. The body, arms, and legs, are covered in tiny short hairs, with occaisional longer ones which act as sensory organs.

Lots of money spiders, linyphiidae, today. All the males were ballooning. Females seemed to be staying put. In one pic you can just see a toothed carapace. Also included someone having a spider lunch. Didn't keep any for ID but did find something new for me. Will check it for tomorrows #Aractober

Two spiders that I seem to find if I'm NOT looking for them:
Antistea elegans is a spider I've wanted to find on the Bucks section of the R. Chess, having years ago seen Doug Marriott's records for it on the Herts side

Tegwyn @arachnoteg.bsky.social · 4d

Yep, outside plant section on the central shelving. You can easily see the webs. Take a few of the black topper caps (pic) and look inside. S.b in the high street and surrounding streets, may be at B&M Look for the retreats with trip wires on fences, brick/stone work. Can be tricky to get out.

Tegwyn @arachnoteg.bsky.social · 4d

If your in that area you should also look for S.bavarica, found lots nearby

A trio of spiders from yesterday's little explore in west Norfolk for #Arachtober Araneus marmoreus and my 2nd ever Zora spinimana from Boughton Fen and a diminutive Euophrys frontalis found in Bodney churchyard. #arachnids #spiders #invertebrates

A large orbweb spider with a pale yellow abdomen which has a dark brown patch towards the rear. The spider is climbing up a brown reed stem.

Side view of a large orbweb spider which has a yellow abdomen with a dark brown patch towards the rear and dark brown lines giving a marbled effect to the flanks. The spider is head down on a green reed stem.

A suprise find, plus a new species for me today #Aractober First noticed the distinctive web, exactly as described. Quick look and there they were... Badumna longinqua. Lots of webs in the Barry B&M, guessing another location for S.Wales. @britishspiders.bsky.social @sewbrec.org.uk @cofnod.org.uk

At least it's a spider 😂 Thanks, could of sworn it had the tuning fork mark! (wasn't wearing glasses 😞)

Surprise find while looking at a stone wall for a theradid. One of the Otter spiders, Pirata/Piratula, a juv. male. They are mostly associated with wet habitats. #Aractober
