Spined Micrathena (Female)

Thanks Tamar! Very interesting! A lesson in sexual dimorphism!

Here's a picture of a male: http://bugguide.net/node/view/668994/bgi...

Thanks for confirming my thoughts, Tamar! If I remember right, the males are almost tubular looking.

This is indeed a female. The males are much less spiny.

Thanks, Keith! I think this one is a female. It was pretty large!
