Spider Identification

[Kron]

I have hundreds of these in my garden however til now I hadn't seen an adult, now that I have I'm quite uncertain as to what they are. They look like a cross between a gnaph and a jumping spider. They live in shiny white cocoons from which they often venture from, body length 1.5 cm for this particular individual, 1st and 2nd legs curl forward and seem disproportionately short (very reminiscent of a jumping spider) young jump adults less so but still do, eye count 8 (a row of 6 then a spaced out row of 2 on top; hard to see eyes due to size) yellow tinted legs, red tinted cephalothorax, abdomen is grey/silver and then hopefully you can see the pattern. This one is probably gravid. quite agile, has a posture that makes it very flat, quite good at hunting small flies that fly by.

Hard to tell for sure, but check out some of the Amaurobius species that are common in the UK. A. ferox, A. similis, and A. fenestralis are all pretty common, and your description of the eye pattern sounds about right for this family.

Nope it doesn't have lace webbing and it's front legs are too short and the pattern has one strong spike like stripe etc I do have some Amaurobius around but these guys are quite different.

They're also escape artists, I've caught 3 so far and they escape every time due to their flat bodies. That includes the one I just showed you, it's vanished, It's like magic. they are also better climbers than the usual Amaurobius, others I've had couldn't climb the plastic walls but this one could with ease.

The way the legs are positioned in the OP makes me think of segestriids, but it doesn't really look anything like the two big Segestria spp. in the UK - and some of the description doesn't fit (eight eyes, for instance!)

Kinda looks like a ghost spider..

I believe I have found it, a Clubiona corticalis, I didn't know they could jump though (and this one (caught it again) jumps a lot, erratically) and this guy/girl is 5 millimetres bigger than they are supposed to be could it be a sub species or something?

also they're supposed to reach adulthood in summer not late autumn

Spiders can vary wildly in size within a single species. Some get huge, some stay small. Happens with all arachnids, actually.
