Sericomyia


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.
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
