Family: Rhagionidae
Subfamily: Rhagioninae
The two most common genera of Snipe Flies in West Virginia are Chrysopilus and Rhagio. The two are separated by the number of spurs on the hind tibia; Rhagio has two while Chrysopilus has only one.
Rhagio has the antennal segments subglobose (the third one sometimes subconical). The sides of the face are usually convex (Leonard, 1930).
The larvae of flies in the genus Rhagio are typically found in rich, moist soil, where they presumably prey on other small arthropods (McAlpine, 1981).
