Kleptoparasitic interactions among animals
Diptera: Anthomyiidae


The bee, Andrena barbilabris, returning to ites nest from a foraging
flight, carefully watched by a satellite fly, Leucophora spec.

Anthomyiidae is a family of rather drably colored flies. In their larval feeding they show a wide range of habits, including saprophagy, predation, parasitism and kleptoparasitism. Species of the genus Leucophora are kleptoparasites of various bees. Female flies habitually follow foraging bees at a fairly constant distance, as if tethered to the bee, whence these flies are called satellite flies (but the name also applies to some other kleptoprarsitic flies with the same habit, such as the Miltogramminae.) Flies of the genus Eustalomyia are kleptoparasites of various Crabronidae, or digger wasps. Knowledge of the hosts of various Anthomyids is still limited. The photos below show a few anthomyiid kleptoparasites with possible hosts.
