Identification
Adult: forewing highly variable - usually grayish-brown with inconspicuous pattern of black streaks and spots; lines broken, obscure; reniform spot blackish, ringed with ground color; black-shaded form "cinereofrons" predominant in some localities; form "telifer" has long black streaks in basal and subterminal areas; hindwing dirty white in male, dark gray in female
[adapted from description by Charles Covell]

Larva: fifth abdominal segment distinctly humped; 5-banded stripe on head; body light brown with contrasting green second and third thoracic segments
Range
all of United States and across southern Canada. (2)
Habitat
deciduous forests; adults are nocturnal and come to light
Season
adults fly from April to September in the south; June to August in the north

See Also
Schizura unicornis has a very similar caterpillar. The head stripes and humped A5 (fifth abdominal segment) of this species are listed as distinctive in Wagner (3) p. 314. S. unicornis also has a white V-shape over A6 and A7 which S. ipomoeae lacks.
