Showing some of the variety that can occur in a local population, all adult female A. marmoreus (identified by the epigyne). I found all of these spiders within about 30 yards of each other.

amazing variations
Thanks for interesting pictures. I've only seen yellow ones.
Do you live near a source of atomic radiation?

I'm glad you liked the pictures. I didn't find so much color variety this year, though. Most of the 2010 population was yellow-orange tinted like the one pictured above.

Guess the radiation levels were down. :) Seriously, though, I'm not sure exactly what factors are involved in determining color from one season to the next.
