Ipimorpha pleonectusa
Even-lined Sallow, Blackcheeked Aspen Caterpillar
Ipimorpha pleonectusa, the Even-lined Sallow, is a noctuid moth native to North America. It is one of two recognized species in the genus Ipimorpha on the continent. The species was described by Augustus Radcliffe Grote in 1873. Adults are nocturnal and attracted to light. The common name 'blackcheeked aspen caterpillar' refers to the larval stage, though specific host plant associations require verification.
