Phidippus audax By Matt Young May 27, 2024 11:00 MST Phidippus audax – jumping spider, often called bold jumper, found in an enclosed, unheated space, Boulder, Colorado, April, 2024. I was interested in the powerful forelegs, if that is the right word (the left foreleg must have been folded under, because a later photograph shows that it is intact). The spider in this photograph was running along the edge of a dish from which it could apparently not get out. Despite the designation jumping spider, it very kindly hung around while I managed a few photographs. To see comments on this post click below:
