What kind of spider is this?

It's not a brown recluse, that much I'm 100% sure about.

I think what you've got here is a juvenile Yellow Sac Spider (Cheiracanthium sp.). Cheiracanthium inclusum and Cheiracanthium mildei are the two common species in North America, but your images are too blurry to make a species ID possible.

These spiders do have necrotic venom, and so there is the possibility that a bite can produce a wound. However, it's very, very rare. In dozens of studied Sac Spider bite cases, only a few showed any signs of necrotic lesions, and those were all mild cases that posed little danger to the victim.

Still, it's not something I'd like crawling in or around my house. :)

I have simply observed a nest, in my lawn, of what looks to be one hundred's of little yellow and black spiders newly hatched...Never obvious them earlier than in my existence.... Being a little bit concerned (Yellow and Black is most of the time natures caution signal) I have performed a quantity of searches... After trawling the online it looks it perhaps be a style of Argiope (black and yellow lawn spider) nevertheless that's a US spider and I am dwelling within the UK... Further shopping indicates their is a 'Wasp Spider' that's observed in Contienial Europe and repeatedly the South Coast of England... Which continues to be a thriller as I reside within the Midlands(England - UK) that's miles from the any coast permit handiest the South Coast.... Should I be charging humans to return and consult with my Garden to peer this infrequent web site or is there yet another style of spider out right here? They aren't hazardous to persons are they I believe??? - my mum could be very anxiouis!!! Damon

Brown recluse, or maybe lynx spider. Kill it. The fact that it isnt very brown is probably because it just molted.

hope he didnt bit u becaues you could possible die in 8 hrs after the toxins enter your blood stream and multiply by the second.

your face.
