Adults are nocturnal and come to light. There is a single annual brood with adults in late summer. Adults have been collected in Alberta from early August through mid-September. The larva was described by Crumb (1956:117) under the name “Rynchagrotis cupida, western larva”. Reported larval hosts include willow and cultivated apple, grape and peach trees, with larvae reportedly causing damage to buds and new growth on the fruit trees (Rings et al, 1992).
