This spider, originally from Europe and Asia, is found sporadically from Nova Scotia to British Columbia, south to Georgia, and westward to Colorado. Although not recorded in the Rocky Mountain states, it is found in Oregon and California. It is also found in many other locations throughout the world.
The zebra jumper is a relatively small Salticid compared to the others listed in this publication. It is readily identifiable by the pattern that is similar in both sexes. The cephalothorax has a white lateral band with additional white hairs in the eye region. Iridescent scales may appear near the eyes. The abdomen has white or light-colored hairs arranged in opposing stripes with a band around the anterior end. The females are often lighter in color than the males and may be mistaken as separate species. Males have very large, dark chelicerae that project forward rather than down as in most other spiders. Females range from 4.3 to 6.4 millimeters in length; males are 4 to 5.5 millimeters long.
This spider is frequently found under stones, in high grass, on bushes and fences, and both inside and on the exterior of buildings. A retreat is frequently spun between cracks and crevices of boards or similar locations. Mating occurs in late spring and eggs are deposited in June and July depending on environmental conditions.
As with other jumping spiders, this species is not considered medically important.
