There were a few tests / studies done wtih spiders, predatorial insects, and common bugs.Nice shots, everyone. What amazes me about jumping spiders is that they are one of the very few spider groups that actually have good vision and you can tell by the way they respond to things around them. 'Makes them look kind of intelligent to me. I also love the colors some have.
Those iridescent fangs certainly are unique. It's no match for the peacock spider though!
I recently saw a post on an arthropod forum that stated that jumping spider females would sometimes act sexually available to males so as to lure them close enough to be grabbed and eaten. Grim but clever.
That's quite possible. Especially when considering the fact that female spiders often eat their mates anyway.
