  marbled bristle fly

  Archytas marmoratus is a tachinid bristle fly and member of the marmoratus species group. It is a larval-pupal parasitoid of noctuid moth caterpillars, particularly the corn earworm (Helicoverpa zea) and fall armyworm (Spodoptera frugiperda). In 1986, it was successfully employed in biological control programs against the fall armyworm. The species has been used in inundative release programs, achieving parasitism rates exceeding 90% in isolated corn fields.
