Size
wingspan about 17-20 mm, based on two Internet photos
Identification
Adult: forewing variably yellowish, orangish, or tan with brown AM and PM lines; AM line a smooth shallow arc, almost straight; PM line a smooth shallow S-shaped curve; two discal spots in median area near costa are same color as AM and PM lines; hindwing similar color as forewing but AM line absent and PM line reduced to short straight portion near middle of wing.

Across southern states from California(1) to Florida(2), north in the east to Massachusetts, Quebec, Ontario, Michigan, and Iowa. (3), (4), (5)
based on an Internet search, this is the only species of Helvibotys or Neohelvibotys with confirmed records north of North Carolina

The larvae feed on pigweed (Amaranthus spp.) and Common Beet (Beta vulgaris)

Munroe in 1976 (and Brian Scholtens in a recent email message via Bob Patterson) said that species of Neohelvibotys cannot be reliably distinguished from Helvibotys except by examination of genitalia.
Other Helvibotys species are restricted to the southern states.
