Interpretive Summary: Many species of soldier flies are beneficial to agriculture because larvae help decompose plant material, although a few species are known to attack living plants, such as grass roots. This publication records a new species that is invasive to the United States, possibly from China or Japan, which is now known to occur in Virginia. It is unlikely to have significant economic impact as they are scavengers feeding on decaying organic matter. This research will enable scientists, quarantine personnel, and others concerned with flies to identify this species if discovered in other areas of the United States.
Microchrysa flaviventris (Wiedemann) (Diptera: Stratiomyidae: Sarginae), a species widespread in the Old World, has been introduced and is apparently established in the eastern United States. Specimens were taken in Alexandria, Virginia in August of 2007.
