Identification
Adults are bumblebee mimics with very large hind femora; larvae with a tube-like breathing siphon at the rear end. Adults may be told from the superficially similar Merodon by the intersection of the M1 and R4+5 veins, which is a right angle in Merodon but a quite acute angle close to the wing edge in Mallota.
