Male antennae are yellow. Wing margins are brown, median line is white. Black marking at forewing tip runs parallel to the costa. Mating occurs at night, and females lay eggs in large clumps on the host plant. Eggs hatch soon after they are deposited, and young caterpillars feed in groups.
Caterpillars quickly complete their development and spin cocoons before winter.
One brood from September-October. If found, populations should be conserved and monitored. GU - Unable to assign rank due to lack of available information. The moths of America north of Mexico, fasc. E. W. Classey Limited and R. B. D. Publications Inc., Middlesex, England.
