Can you post a picture? Are you picking them up and then they bite you or what? I think that virtually all spiders are poisonous; however, very few are dangerous to people, and most can't or won't bite. Are you positive these are spiders?
By your description they are some species of orb-web spider, but I need more information.
the bite was an accident. cutting grass, did not see the web until i ran into it. yes it it is a spider. 8 legs, spins webs, eats insects. as soon as it gets warmer i will try and get a picture. Haven't seen them much since the temp. dropped. any way is you go further down on this forum some one posted some pictures.

I would be comforted by the thought of Princess having a good home, but that doesn't look a bit like her.
