Cyclosa conica is still fairly easy to find in wooded areas . I hope plenty of them survive the winter and reach adulthood. Here are some of the ones I've found recently. @britishspiders.bsky.social

When I find Cyclosa conica I like to keep an eye on them, to see how they embellish their webs. These two have added lines of birch seeds. @britishspiders.bsky.social

This zebra jumping spider, Salticus scenicus, kept trying to balloon from the gatepost, but didn't succeed whilst I was watching it. At least, I think that's what was happening. Iken, Suffolk, UK. @britishspiders.bsky.social

On Friday at Newbourne Springs in Suffolk, I found a young male Araniella sp. attacking a bibionid fly on a wide path. After about two minutes the spider gave up and walked off. The fly survived the attack. Araniella are orb web spinners but there was no web nearby. @britishspiders.bsky.social

Well done All Saints' Church, Chevington, Suffolk. It's great that, on the display board in the churchyard, a Marbled Orb-weaver gets a special mention. For those interested in their churchyard management project here is the link www.achurchnearyou.com/church/1908/... ‪@britishspiders.bsky.social

Not #spiders but #Pseudoscorpions, mini-marvels of the #arachnid world. For more information on their quirky lives, see our factsheet 8 at britishspiders.org.uk/factsheets.

A Daddy Long-legs Spider Pholcus phalangioides showing off its amazing predatorial skills by silk-wrapping the rear end of a Woodlouse Spider Dysdera crocata while keeping well clear of its formidable jaws. For more info on both species see our Factsheets 3 and 17 at britishspiders.org.uk/factsheets

A spider for Halloween, but not a scary one. It's a rather attractive Gorse Orbweaver (Agalenatea redii) I found today near Mildenhall, Suffolk. @britishspiders.bsky.social #arachtober

I only found two Steatoda albomaculata at Lackford Lakes yesterday (12 June) and their markings and colouration were quite different. @britishspiders.bsky.social @suffolkwildlife.bsky.social

Zilla diodia is easy to find at present in the countryside of West Suffolk, or the part that I live in at least. Here is a selection of ones in the local hedgerows. @britishspiders.bsky.social

I couldn't find the spider I was looking for today #lackfordlakes in Suffolk, but these were adequate compensation

As @britishspiders.bsky.social have pointed out, some spiders are still active in December. This male Alopecosa barbipes and female Drassodes (probably pubescens) were caught in pitfalls on Suffolk breckland in the past few days. (Both were released after being photographed). #winterspider
