 "Melaloncha" is organized into two subgenera, "Udamochiras" (51 species) and "Melaloncha" (117 species).The parasitization of honey bees and native stingless bees causes premature mortality of workers and is a drain on the colony.The effects of "Melaloncha" parasitism on commercial beekeeping, including efforts to keep native tropical stingless bees (meliponiculture), and the scale of financial losses due to these flies has not been studied.
