Widespread and conspicuous, but generally uncommon in Maryland. Adults fly mostly June through October. Frequents deciduous forest openings and edges. Adults visit a variety of flowers. Larvae live in decaying heartwood of deciduous trees, including rot holes. (Skevington, 2019)
The largest flower fly (family Syrphidae) in Maryland. Said to mimic queens of the Southern Yellowjacket (Vespula squamosa); reported size is 16.5-23.6 mm (Skevington, 2019). Emits a loud buzz, possibly the only Maryland flower fly to mimic the sound as well as the appearance of a wasp or hornet. Readily identified by the large size, buzz, and distinctive orange, black, and yellow abdominal pattern.
