Pantropical Jumping Spiders in Florida: EENY-158/IN315, rev. 9/2002

Abstract

Jumping spiders, or salticids, are so named because they have a highly coordinated jumping ability with which they capture prey and traverse from plant to plant. Their sense of sight is extraordinary for invertebrates; they can see in color (DeVoe 1975), and the large front eyes focus on objects (Land 1972). Many are marked with
contrasting colors or bands, especially the males who display this ornamentation while dancing before females to win acceptance for mating. Jumping spiders as adults may be as small as 1 mm in length or as large as 23 mm, but most are 5 to 10 mm. All jumping spiders are harmless to humans, although the larger species can give a locally painful bite if roughly handled. This document is EENY-158 (originally published as DPI Entomology Circular 199), one of a series of Featured Creatures from the Entomology and Nematology Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.
