Life Cycle
Eggs (at least in M. minutus) are laid in a mass on the stem of a plant, such as a stiff blade of grass:

This unusual (for an asilid) egg-laying habit is shared with the related genus Mallophora (see genus page). Certain Mallophora are reported to be parasitoids of scarab beetles, and the unusual egg-laying habit is thought to aid in the dispersal of tiny larvae in search of hosts. Given the similarity of egg-laying habits in at least some species of the two genera, it seems likely that Megaphorus is also a parasitoid or predator of ground-dwelling insect larvae. See Mallophora account for more information.
