Description
 
 

Bare-bellied falsehorn is a small, wasp-mimic hoverfly. It occurs in northeast and north-central United States and in adjacent Canadian provinces.

Adults are to (9 to 14.5 mm) long.

The protruding mouthparts (proboscis) is short and fleshy.

The thorax and abdomen are black with yellow markings. The exoskeletal plate on the underside of the thorax that is associated with the second thoracic segment (katepisternum) has a continuous (uninterrupted) band of hairs on the rear margin. The plate on the underside of the third thoracic segment (metasternum), between the bases of the middle and hind legs, has no hairs, but this is not visible without magnification.

Abdominal segments 2, 3, and 4 each have a single yellow band. The hairs on the rear margin of segment 5 are black.

The outer part of the wing is mostly smoky brown, the inner part mostly clear. The basal medial cell (bm), discal medial cell (dm), and posterior cubital cell are mostly free of hairs, but this is not visible without magnification. There is a spurious vein between the radius (R) and media (M) veins. The cross-vein that runs between the radius and media veins (R-M cross-vein) does so beyond the middle of the discal cell. The anal cell is long and is closed near the wing margin. The R5 and M2 cells are also closed.
