Pero ancetaria – Hubner’s Pero

Hodges # 6748

Caterpillar foods: alder, buffaloberry (Shepherdia canadensis), Black Cherry, willow  (Bugguide)

Pero honestaria, Pero ancetaria, and Pero morrisonia are difficult to differentiate in photos – they need to be dissected to be sure of the correct ID. (Bugguide lists some ways to visually distinguish these species.)  The following are my best guesses without dissection.
