Infrequently reported in Maryland. Adults have been noted visiting flowers of Crataegus, Physocarpus, and Rubus, but can also be observed resting on leaves in forest understory. Larvae are filter feeders in water-filled tree holes (Skevington, 2019).
One of several flower fly (family Syrphidae) bumble bee mimics. (Note that several robber fly species also mimic bumble bees.) Abdomen variable but usually extensively yellow pilose, covering tergites 1, 2 (partly) and sometimes 3 (BugGuide). Identifiable with care from photos.
