Phylogenetic sequence # 930098
Explanation of Names
IPOMAEAE: from the genus name (Ipomoea) of morning-glory, allegedly one of the larval foodplants, and the origin of the common name Morning-glory Prominent
Lafontaine & Schmidt (2010) listed eight species of the genus Schizura in America north of Mexico. (1)
wingspan 36-47 mm
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
all of United States and across southern Canada. (2)
deciduous forests; adults are nocturnal and come to light
adults fly from April to September in the south; June to August in the north
larvae from May to October
larvae feed on leaves of beech, birch, elm, maple, oak, rose, and other woody plants; probably not morning-glory (3)
Life Cycle
one generation per year 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.
