In forensic entomology,fly data including maggot age are frequently used to help estimate the time since death.Accurate identification of the maggot to species is critical for time since death estimations. However, within a family, maggots are notoriously difficult to identify to species.In this study, we employ phylogenetic datafrom the mtDNAgenes COI and COII to identify an unknown maggot to species (member of the family Sarcophagidae) harvested from a cadaver in June 2009 in Harrison County, Texas. The most closely related species to our unknown maggot was SarcophagabullataParker 1916, a somewhat common carrion-feeding species in southeastern United States that is now gaininggreater recognition as a forensically significant species.
