Gymnoclytia immaculata
Gymnoclytia immaculata is a North American tachinid fly species in the family Tachinidae. As a parasitoid, its larvae develop within host insects rather than feeding independently. The species has been recorded from hosts in both Lepidoptera and Hemiptera, specifically the armyworm moth Pseudaletia unipuncta and the stink bug Euschistus variolarius. It occurs across a broad geographic range from British Columbia to Quebec in Canada, throughout the United States, and south into Mexico.
