One study of the species Stelis ater found they differed a bit from other thieving bees by being hospicidal (host-killing) at all larval stages, and neither it nor its host larva move much, so it is simply a matter of chance when its growth brings it into contact with the host rather than with just the provisions. This is in contrast to other kleptoparasitic bees which usually have their more mobile first instar larva kill the host larva.[3]
