Episyrphus
''Episyrphus'' is a genus of hoverflies in the subfamily Syrphinae. Larvae are predatory, often on aphids. Two subgenus, subgenera are recognized, ''Episyrphus'' and ''Asiobaccha''. Species of the latter are distinguished by a Petiole_(insect_anatomy), petiolate abdomen. It has been claimed that classification within the genus ''Episyrphus'' needs revision, due to the poor clarity of species names and distinguishing characteristics between them. Characters such as the colors on the abdomen or of the pile on the frons and scutellum (insect anatomy), scutellum, often taken as diagnostic, have been found to depend on temperature in studies on ''E. viridaureus''.
