Notes on three nests of the large carpenter bee Xylocopa (Neoxylocopa) frontalis (Olivier) (Apidae) attacked by the parasitoid Leucospis leucotelus Walker (Leucospidae) are presented. We observed that host brood cells contained from four to 12 parasitoids (adults or immature) which allowed us to identify this Leucospis species as a gregarious parasitoid. This was the first record of a gregarious Leucospis species attacking X. frontalis nests.
