There are over 70 described species of Pseudacteon fly. They are also known as ant-decapitating flies due to their parasitic larval stage. An egg is injected by the female fly into the shoulder joint of an ant worker. Soon after, the egg undergoes rapid inflation as it appears to absorb ant hemolymph. This first instar larva migrates into the ant head and consumes the jaw muscle and other tissues, leaving the mandibles hanging and preparing a future exit space. After about two weeks, Eventually, the ant worker is termed a "zombie" because the fly larva has effectively taken control. The worker leaves the nest and dies in the leaf litter or in a crack in the soil. As it dies, the ant's head falls off, apparently when the fly larva [1]wo[2]releases an enzyme that dissolves the membrane attaching the ant's head to its body. The fly pupates in the detached head capsule, requiring a further two weeks before emerging through the ant's mouth. Selected speciesSpecies include:
