Found this spider in Assen(NL) can anyone identify it?
That’s an Araniella orbweaver, Araniella cf. cucurbitina.
Also known as cucumber spiders.
Probably a crab spider Misumena vatia (NL: gewone kameleonspin D: veränderliche Krabbenspinne). They vary in colour quite a lot. Usually they are sitting on a blossom of similar colour and wait for prey.
General shape (crab spiders have prominently larger front legs) doesn’t check out.
No, this one is actually looks green.
I think I already found it, it’s about 3.5mm long, bright green abdomen with green legs and a brown head, it looks like a Green Meshspider(Nigma Walckenaeri). I just wasn’t sure because most descriptions of this have more yellow-ish legs, these are green all the way until the legs are too thin to really show visible color.
For the one I proposed, yellowish green is also possible. The one in your link seems to have a hairy abdomen, which I don’t see in your picture. Also it seems to be much darker greenly coloured. (Just my two cents, but I’m no expert)
Maybe a yellow sac spider?
