Newly emerged females of Megaselia sextovittata sp. n. and M. chapmani Borgmeier are reported imbibing haemolymph from the pupae of Chalicodoma sculpturalis (Megachilidae) and Anterhynchium flavomarginatum (Vespidae, Eumeninae). Pupae thus attacked subsequently died.The larvae are reported to be parasitoids of the larvae of these two species of Hymenoptera, butpossibly only develop in hosts that are already debilitated or moribund. No newly emerged flies were observed ovipositing into or onto living host pupae. The feeding on the haemolymph of potential host pupae, by causing the death of those thus attacked, is likely to prevent the normal defensive response that would inhibit the development of the fly larvae in still living pupae. This may have been one route by which the evolution of the parasitoid habit in Phoridae evolved.
