First Documented Wild Population of the "Hunter Fly", Stein (Diptera: Muscidae) in North America.

is a member of the -group of ( Hennig 1964) and is a capable generalist predator in its larval and adult stages. is common in greenhouses worldwide, however, there are few documented cases of its presence in the wild. Here, we estimated presence in the southeastern USA peach orchards using pan traps. Over two years, a total of 717 specimens were collected from both commercially managed and fungicide-only managed peach orchards. is a known biological control agent in artificial greenhouse settings, but its impact on pest species in the wild is still unknown. For the first time in North America, we document an established wild population of provide an overview of basic identification, and review potential benefits for biological control.
