Identification
The only genus in the Syrphini that has long hairs on the lower lobe of the calypter. This is used to separate the genus from all related genera.
In most Syrphus (but not in all and also in some species in other genera) the mesonotum is dull. Many Syrphinae have a strongly shining mesonotum, sometimes with two whitish stripes near the anterior margin. Paul Beck's comments)
