Sercomyia are large flies with species that are bee mimics both short pile and long pile. Sericomyiine flower flies are common in boreal forests across the Holarctic region and southward at higher elevations into the Oriental and Neotropical regions.[1] Sericomyia species have larvae of the rat-tailed maggot type, often found in ponds rich in decomposing vegetation where they filter out microorganisms as their food [2][3][4]
They have an oval flagellum with a plumose arista. The eye are bare and narrowly to broadly holoptic in male. The wings are darkly colored along the anterior margin. Cell r1 is open. The stigmatic crossvein is absent. The cell r4+5 with long petiole, longer than humeral crossvein. The vein R4+5 is straight to moderately sinuate.[5]
