The twin-flagged jumping spider is small and mostly brown or grey, named for two pale, flag-shaped markings along the sides of the abdomen. Iridescent scales around the eyes and on the male's pedipalps can appear white, green or pink depending on the light.
It hunts by day in leaf litter, on tree trunks and on the walls of buildings, relying on sharp eyesight to stalk small insects rather than spinning a web. It is most active in the early morning hours across the southeastern United States.
