Zygoballus sexpunctatus is a species of jumping spider which occurs in the southeastern United States where it can be found in a variety of grassy habitats, including old fields, river terrace forests, flatwoods, Florida Sand Pine scrub, Slash Pine forests, Appalachian grass balds and rice fields. The range of the species extends from New Jersey to Florida and west to Texas, although it is most commonly found in the southern states. The specific name is derived from the Latin sex meaning "six" and punctum meaning "spot", in reference to the six spots that typically occur on the abdomen of the male.
Adult spiders measure 3–4.5 mm long. The cephalothorax and abdomen are bronze to black in colour, with reddish brown or yellowish legs. The male has distinctive enlarged chelicerae (the mouthparts used for grasping prey) and front femora (the third, and typically largest, leg segments). Like many jumping spiders, Z. sexpunctatus males exhibit ritualised courtship and agonistic behaviour. (Full article...)
