Moths in Wyoming

One of the commonest moths dwelling in Wyoming is the miller moth infesting homes and backyards, the peak season being between May and June. The adults do not damage fabric or property but the larval form feeds on leaves of trees like oak, willow, and poplar causing defoliation. The polyphemus and imperial moths of the Saturniidae family are considered the largest here.
