For the record, I'm an arachnophobe. Over the years, I've managed to desensitize myself to the point where I won't actually run out of a room, screaming when I see a spider, but I'm still not very fond of the evil, little bastards.
In spite of this, I can't help but to be mesmerized by this video of jumping spider mating behavior. Basically, what's going on, here, is that the male wants to have sex with the female. Unfortunately, the female tends to view all moving things as food, so the male needs to (very, very carefully) prove that he's actually a male jumping spider by sending her the proper signal.
Let's hope that she's in the mood.
