Caption:
Stalk eyed fly - family Diopsidae, genus Teleopsis (?). The males of stalk eyed flies compete for females based on the width of their eye stalks. Usually males have much wider stalks than females, but some species lack this dimorphism. The eye stalks are thus a product of sexual selection based on within-sex competition like the antlers of elk.
