Selenia overwinter as pupae, and the moths fly in spring and early summer
The genus Selenia contains 4 European and 2 widespread North American species, both of which occur in Alberta. Thorns are medium-large (3.5 - 4.5 cm wingspan) moths with angular, scalloped wing, mostly rust and yellow-brown in color, and banded with darker shades on both sets of wings.
Adults are both diurnal and nocturnal, and come to light. Selenia are single brooded and overwinter as pupae. The larvae, which are solitary defoliators, are exceptional twig mimics.
Common widespread moths; none are of conservation concern.
Selenia larvae feed on the foliage of a variety of deciduous trees and shrubs in a number of different families.
Europe and North America. Widespread in the wooded parts of North America. Both North American species occur in Alberta.
