What is the easy way to confirm if a fly is a hoverfly?
As for many Diptera looking at venation characteristics takes identification one stage further. To confirm an insect is a hoverfly one of their most characteristic features is the presence of a longitudinal false vein in the wing. In hoverflies a greater part of the edge of the wing is without veins. The vein running all the way to the edge in most flies (radial), only reaches the last transverse vein, not the edge in a hoverfly's upper outer cross vein (A) and lower outer cross vein . Another feature of hoverflies is the so-called 'floating vein' (B). This vein just ends nowhere. Usually veins end either at the edge of the wing or in another vein. Both these features being present means you are actually looking at a hoverfly.
