Zelus longipes

Zelus longipes is an assassin bug that is a member of the Harpactorinae subfamily. Its distribution ranges include southern North America, Central America, and South America, especially in agroecosystems in Brazil.
Zelus longipes has been considered as a potential biocontrol agent, as it prefers caterpillars of Spodoptera frugiperda, which is a moth that is a pest in cornfields. The species is a generalist predator, commonly used to combat picture-winged flies, which cause damage to sweet corn yields in Florida. Z. longipes prefers smaller caterpillars, probably because there is less risk of injury while subduing smaller prey.
