Physical Characteristics

Large syrphids with cylindrical bodies, mimic wasps, particularly hornets. They have a buzzy flight, likely due to mimicry.

Identification Tips

Look for their large size and cylindrical shape; they resemble wasps in appearance.

Habitat

Larvae feed on wet decaying heartwood in rot-holes.

Distribution

Worldwide, with the highest diversity found in southern Asia. In the studied area, one species is widespread in the east, another in the southeastern U.S. (NC-FL-TX), and one in the southwestern U.S. (AZ-NM).

Diet

Larvae feed on wet decaying heartwood in rot-holes.

Life Cycle

Active during summer; M. virginiensis observed from May to September (to November at low elevations), and M. scutellata from May to June.

Ecosystem Role

Pollinators and decomposers due to their larvae feeding on decaying material.
