For terminology see Speight key to genera and glossary The second antennal joint is longer than broad, and the third joint is two and a half to three times as long as the other two combined. Pteropleura with black pile.The lateral margins of tergites two to five alternating black and yellow, with arcuate abdominal bands interrupted and broader, less arcuate abdominal fasciae, with the front edge of the interrupted fasciae being almost parallel with the anterior margins of the segments. The wing microtrichia is well developed, and the wing vein R4+5 is clearly dipped into cell r4+5. There is no yellow spot above the fore coxa. [4]

Spilomyia sayi, the Four-lined Hornet Fly, is a fairly common species of syrphid fly. This species is found from western Canada to northeastern North America. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae are known as the short-tailed larvae, suited for moist areas such as rot holes of trees. It is a wasp mimic.
The genus Chrysotoxum consists of large, wasp-mimicking species. The adults are distinguished by very long antennae, oval abdomen with yellow stripes, and yellow patterns on the thoracic pleurae . The species of Chrysotoxum are chiefly Holarctic in distribution. . The species in this genus,, are mostly very uniform in structure and colour and are separated with difficulty. Larvae are specialized in preying upon root aphids associated with ant nests.
