Descrição

Jumping spiders, as a group, are often furry, have exceptionally keen vision (two of the eight eyes face forward and appear goggle-like), and characteristically move in a jerky gait. Most are remarkable jumpers. Silk-spinning is limited to a single "tether" line for safety when exploring or when jumping great distances, and for making cocoons to hide in and for eggs. The tan jumping spider usually lives on tree bark and is camouflaged with grays, tans, and browns, with flecks of black, white, and sometimes reddish patches, to blend in with its background. The color pattern is quite variable. Some individuals have a zebralike look while others appear more uniformly gray. There is usually an undulating pattern on the abdomen. The bodies are rather flattened. The pedipalps (fingerlike appendages near the face) are fuzzy and usually white. The chelicerae (fangs, often hidden behind the pedipalps) are fuzzy with long white hairs on males, and are black, shiny, and hairless on females.
