Driving through Cardiff decided to visit a few stores with outside garden plant sections. In Rumney B&M and Cardiff Bay Home Bargains was able to find more B.longinqua, a few webs in the first but no spiders. 2nd had lots of webs, juv and possibly adult. @britishspiders.bsky.social @sewbrec.org.uk

Today, I present to you a gorgeous male Larinioides sp.

As adults, male orb weavers will leave their webs to look for a female. This is why one encounters male spiders strolling about.

They mean no harm. They are just looking for love.

#inverts #spiders ♥️🕷️

Frontal view of male orb weaver (Larinioides sp.) gazing into the camera. The spider has a brownish red colouration and light brown patterns.

Dorsal view of same spider. Males of this genus have quite long legs compaired to the females. This is nicely visible on this photograph since all four legs on one side are neatly stretched out. One the other side the first leg is angled, possibly providing the spider a better hold onto the wall it sits on.

Shaken from bamboo today it's Tetragnatha, Long jawed orbweb spider. The sternum patterns can help divide them into two groups. T.extensa/pinicola have a yellow triangle, the others plain brown. #Aractober This one showing the classic pose

Some nice spiders

Found lots of tiny juv. ant mimics amongst pea gravel today. At least one looks like Phrurolithus festivus to me @britishspiders.bsky.social #Aractober

Really awesome to see an adult male of the rare Glyphesis servulus in Cambridgeshire recently. A right whopper at 1mm! 😁 @britishspiders.bsky.social @cofnod.org.uk @graemelyons.bsky.social @chalkspring.bsky.social

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

Tegwyn @arachnoteg.bsky.social · 4d

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

Tegwyn @arachnoteg.bsky.social · 4d

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

Tegwyn @arachnoteg.bsky.social · 5d

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.
