Not a typical jumping spider Lyssomanes has very long and slender legs, and prefers to move by running and using short leaps as opposed to the jumps that characterize most members of the salticid spider family. Lyssomanes jumping spiders are diurnal sit-and-wait predators of dipterans and other soft-bodied arthropods. They prefer to sit on leaves that are exposed to the sun, waiting in ambush for a visitor on the upper surface to cast a dark shadow.
