Female Jumping Spider (Sitticus fasciger)

click for large

I was snooping around outside of the house today looking for something to shoot in my little studio, and I found three of these gals. This is a female Sitticus fasciger, the males have smaller, more slender abdomens, and larger, very much less furry, black palps. For an informative paper on behavior and identification of this species, look here.

Sitticus fasciger is originally from Asia, specifically the Russia/China area. They are almost always found in conjunction with man. Their favorite habitats are manmade structures like stone walls, houses, building walls and such, which is exactly where I found this girl. They were apparently introduced into the US in the 50's.
