Within these bare areas, the larvae also defoliate native shrubs including four-wing saltbush (Atriplex canescens) and sagebrush (Artemisia spp.).

[7] The miller moth is a seasonal nuisance in the spring in states including Montana,[3] Texas, Oklahoma, Colorado, Wyoming, New Mexico, and Kansas, as they hatch in the low-lying farmlands, then migrate to higher elevations for the summer.

With their very small bodies, they enter homes (attracted by the light) in the evening through any available crack or crevice (doorjamb, chimney, etc.)

They are known to travel to alpine climate regions in late June and early July where they feed at night on the nectar of wildflowers.

Army cutworms are one of the richest foods for predators, such as brown bears, in this ecosystem, where up to 72% of the moth's body weight is fat, thus making it more calorie-rich than elk or deer.
