Larvae of Megaselia minor have been found to develop inside dead adults of Pentatoma rufipes and Palomena spec. (Heteroptera: Pentatomidae) that were killed by a common fungal entomopathogen, Beauveria bassiana. Hyphae of B. bassiana growing inside the pentatomid cadavers seemingly served as the food of the M. minor larvae. In a single cadaver, from 2 to 11 phorid larvae have been recorded. Some of these larvae were parasitized by Orthostigma cratospilum (Hymenoptera: Braconidae). Poland-, Warsaw-area, Dziekanow-Lesny none
