Each species of
Coelioxys is a cleptoparasite only of certain host species. A female
Coelioxys can use its sharp abdomen to pierce the cells of other
Megachile species where an egg is then laid in the cell. The egg of the
Coelioxys hatches before that of the
Megachile and the newly-hatched larva crushes the
Megachile egg with its large jaws. The
Coelioxys larva can then feed on the contents of the cell. Pupation occurs within a cocoon spun within the host cell where the larva overwinters as a prepupa. The genus
Anthophora excavates nest burrows in sandy soil or rotting wood, where they may also become the hosts of
Coelioxys larvae.
Female
Coelioxys should be treated with care as they may sting; males are said to emit an unpleasant odour when handled.
