Aside from a reddish-brown hue on its wings, the features of the Ruby Quaker are so variable, identifying one can prove difficult.
The common Ruby Quaker is a moth of many variations. Forewings may be dark brown or pale ivory, or something between these two poles. An auburn tone in many individuals informs the 'ruby' part of its name. Two large spots on each forewing are separated by a brown patch. The thorax is furry and the antennae have comb-like teeth on both sides of them. This moth is nocturnal, but is attracted to lights. It may also come to a sugar bait, usually made from ripened mashed bananas and sugar. Adults are most active in early spring and summer.
Caterpillars for this species feed on a variety of deciduous tree leaves. Aspen, cherry, maple, oak, and poplar are common food sources. One brood is produced each year, but there are enough eggs to allow this moth to be a common sight every spring.
