Senotainia vigilans
satellite fly
Senotainia vigilans is a satellite fly in the family Sarcophagidae, subfamily Miltogramminae. The species is a known parasite of solitary wasp nests, particularly those of the thread-waisted wasp Ammophila procera. Female flies follow prey-laden female wasps back to their burrows and deposit live larvae at the nest entrance. These larvae then enter the burrow and parasitize the developing wasp larvae. The species was described by Allen in 1924.
