enter image description here]([![enter image description here Can someone tell me which spider this is please? I've found a few of them in my home in North-London, are they poisonous?

  • $\begingroup$ Can you please add where you actually live? $\endgroup$ – Chris Mar 15 '18 at 12:19
  • $\begingroup$ Im North London. Also this one is yellow/brownish with black markings but I have found others with a darker purple back.. $\endgroup$ – C.T Mar 15 '18 at 12:27
  • $\begingroup$ I have taken to color correct your image so the spider can be identified easier. $\endgroup$ – Chris Mar 15 '18 at 12:35
  • $\begingroup$ @Chris your color correct makes the spider look green on both of my screens. I'd suggest having at it again :p $\endgroup$ – theforestecologist Mar 16 '18 at 1:20

It think this spider is a Tegenaria domestica also known as the barn funnel weaver in North America and the domestic house spider in Europe. See here or here (picture taken from the first link):

They are not poisonous and usually avoid confrontations, but can bite.

  • $\begingroup$ That's really informative, thank you for your help. $\endgroup$ – C.T Mar 15 '18 at 12:56
  • $\begingroup$ Does this species ever have a greenish hue to it, or are you putting that down to the OP's lighting? $\endgroup$ – rotaredom Mar 15 '18 at 13:43
  • $\begingroup$ @rotaredom I think this is due to the image. I have corrected the color already, have a look into the edit history to see the original version. $\endgroup$ – Chris Mar 15 '18 at 14:19
  • $\begingroup$ Ah, gotcha. Looks like you've got it nailed, then. $\endgroup$ – rotaredom Mar 15 '18 at 16:57

    $\begingroup$ I'm not convinced this is the same species, actually. $\endgroup$ – theforestecologist Mar 16 '18 at 1:22

Very nice, indeed! This is a Spitting Spider (one of the Scytodes species, but I'm not sure which is most likely over in the UK). That's a good photo, by the way. This spider is easily told in the wild by its odd-shaped, domed carapace, with the 'Rohrschach-blot' design around the edge, and the spindly, banded legs. It's a slow-moving, very mild-mannered spider, with one of the more fascinating methods of catching prey: basically it spits a sticky saliva in zigzags that restrains the potential food, then rambles up and bites it. I include a photo and a couple of links for your enjoyment - using a familiar species from the US, Scytodes thoracica.
