Spider - Parasteatoda tepidariorum

Spider - Parasteatoda tepidariorum
Southwestern, Pennsylvania, USA
November 8, 2007
Size: less than pencil eraser
Found this tiny thing in the depths of my basement. I originally spotted the egg sacs first. Don't know if this little one belongs with the eggs or not. Spiders love my basement.

Spider - Parasteatoda tepidariorum Spider egg sacs - Steatoda triangulosa

Common house spider (Achaearanea tepidariorum)
I believe that the spider is a female Common house spider (Achaearanea tepidariorum). I don't know if the other items are related or not? Most of the images of eggs for this species appear to be teardrop shaped, and have a brown papery consistancy.

Common house spider
Thanks for the fast ID John! I probably have hundreds of these little guys hiding all over, but this is the first one I've seen up close. I'll do some checking on the eggs. Thanks again!

old egg sacs are from a Steatoda triangulosa.

Cobweb spiders
Fanatastic! Thanks for the ID. I can remove them now since they are old!
