The four Green Meshweaver females on the forsythia have given me the slip, quitting their webs simultaneously & vanishing altogether. Presumably all are mated & have gone to secrete their egg sacs out of harm's way. Two males linger under vacated webs.🕷💚🍃

A rather small spider found in a bit of the lichen Evernia prunastri in April 2011 at @SelborneSoc #PerivaleWood. Any thoughts on what species it might be. @BritishSpiders @amentsoc @BritEntSoc

A chance meeting (my first) with a Buzzing Spider (Anyphaena accentuata) this afternoon. Thought its hazel leaf retreat must be the mesh web of Nigma but out popped this beauty instead! Will return in better light to try for more pics. Bransford, Worcs.🕷💚🍃

Garden wildlife. Garden spiders (Araneus diadematus) can build impressive webs, at least in terms of the distance of the support lines. For the last 2 days this one has built a web where the lines go from the gutter of my kitchen roof to plants below, a distance of just over 2m.

On tenterhooks this afternoon, watching a Green Meshweaver male put everything on the line for love. The female looked big, was she mated already or just well fed? A crucial distinction. He tiptoed forward...to the sanctum of the web...& success 🕷💚🍃

This is Zoropsis right? My aunt says it ate an Araneus diadematus which seems odd to me

Garden wildlife. 1/2. From the fence/house last night. A male Anyphaena numida was on the prowl, as were probably 2 (though the photos were taken at different times, so maybe the same one) male Amaurobius similis. #londonwildlife

Garden wildlife. A couple of Amaurobius similis on the fence last night. I thought one was a male (1st image and top one in the 2nd video) and the other a female, but that also seems to have palps. I've been advised that that one, and with its back legs moving, is web building.

Just had to rescue this enormous bastard from the kitchen sink. Mission Accomplished. Hopefully not in a Bushian way.

2/2. and a Harvestman (Odiellus spinosus). Finally a couple of Amaurobius similis - one wandering on the fence and another one just by its web. I've included a short video of the second as its abdomen was moving in and out as if breathing! That's something I've not seen before.

Garden wildlife. 1/2. Some other spiders from last night on the shed, house and fence. Firstly a couple of Anyphaena numidas, followed by a Zygiella x-notata, then two Steatoda nobilis seemingly being quite friendly,

Garden wildlife. 1/3. Last night I found 10 Segestria florentinas! They are still all relatively close together, and 3 were in an area I'd not noticed or properly checked before on one side of the garage door frame.
