This is the male of a species that parasitizes Megachile (leaf cutter nests) by laying their eggs in the nest of the host, after which the young Coelioxys sodalis emerges and kills the host larvae and consumes the pollen and nectar of the host's young. About 20% of all bees work on this model.

Megachile farinosa: a rather rare species and with conspicuous red legs, a feature which is very uncommon in European Megachile. This species flies in high summer and the female gathers pollen only on the flowers of Vitex agnus-castus.Some alternative or past names for the species include Chalicodoma farinosa or Pseudomegachile farinosa.
