Polidori, C., Disney, R. H. L., Boesi, R. & Andrietti, F. 2005: Association of the scuttle fly Megaselia leucozona Schmitz (Diptera: Phoridae) with sweat bees (Hymenoptera: Halictidae), with a description of the male fly. - Entomol. Fennica 16: 144–150.
Megaselia leucozona Schmitz (Diptera, Phoridae) is reported from nests of Lasioglossum malachurum Kirby and Halictus scabiosae (Rossi) in Central Italy. The flies patrolled two nesting sites of the hosts and sometimes mated close to their nest entrances before entering. Observations agree with the general behaviour reported for other Megaselia species associated with fossorial bees and wasps. The hitherto unknown male of M. leucozona is described, and the original description of a female is augmented and modified. This is the first report of a scuttle fly associated with nests of Halictidae in the Palaearctic Region.
