Zelus renardii, the leaf hopper assassin bug, is a predacious insect contained within tribe Harpactorini. Diurnal and found on both wild and crop plants, Z. renardii has spread from its native habitats in western North and Central America into three other biogeographic regions across the globe. Zelus renardii is considered a sister species to Z. cervicalis, as they share two unique characters: the lateral margins of dorsal phallothecal sclerite are recurved and the medial process is strongly hooked apically.
