Menemerus bivittatus -- The Wall Jumper - Menemerus bivittatus - Male
Torrance, at Madrona Marsh, Los Angeles County, California, USA
May 27, 2005
Size: 1/3 inch
This species inhabits walls, hence the name wall jumper. There is a marked dimorphism between males and females, but their wall habitat is the giveaway that they are related. The white central stripe of the male's carapace, as seen in most of this species' range, in southern California broadens frontally so that the entire interocular area is white.

Nice portrait.
I see you managed to capture it in its natural habitat, too:-) Hahahaha! Seriously, this is a really nice, clear image. Thank you for sharing.

I never see them on anything
I never see them on anything but walls and related structures--I'll be posting a nice female on a chain link fence when I get to it. These are cosmopolitan, which I assume means they travelled from place to place as shipboard passengers--quite probably welcome ones, too. Flies seem to be a main part of their diet.
