Spotting

Description:

I think it's a ground spider, but I'm not sure. Small, about 4mm body length; black with white markings down the center of its abdomen. Very active and difficult to photograph, as it wouldn't stop for more than half a second at any time.

Habitat:

Rocky, barren land on Island (Isla del Sol) on Lake Titicaca, at about 4000m above sea level.
