Common Dainty

"Baccha elongata" is a species of hoverfly in the genus "Baccha". The long, very slender body of this hoverfly is unmistakable. Members of the eristaline genus "Sphegina" are also very slender and can be found in similar habitat but those flies have a rather different enlarged hind femur, whereas in "Baccha" this feature is slender.
