Classification of moths and other insects can sometimes change, and it is possible that this one will, but the Glover's Silkmoth is generally considered a subspecies that resides in the western states and provinces and as well as some central provinces. The Columbia Silkmoth is found in the Northeast and Great Lakes area, so the moth's location is really helpful in trying to determine its identity.
Glover's Silkmoth is a rich brown color with a white line crossing the lower part of the wings. Beneath the white line is a band of gray-brown and a tan border. A thin curvy line undulates in the tan area, creating 'u' shapes. At the wing tips, a white squiggly line looks almost pearlescent on a pink background, and a dark blue and black eyespot is next to it. A large white crescent sits on each hindwing and is visible when they are spread open and flat. Smaller white dashes sit in the center of the brown parts of the forewings. The moth has a hairy, gray collar by the head. Its hairy thorax is the same shade of brown as the wings, and a large white patch is near the head. Antennae are large and thick with comb-like teeth. Legs are brown and also thick with hair.
Caterpillars are green or yellow. Depending on its maturity, it may be yellow and black with tufts of black spikes in rows on the body, or is could be green and covered in white, yellow, and blue knobby bumps. It feeds on an assortment of plants like buffalo berry, Russian olive, willow, larch, bitter brush, chokecherry, and wild roses. One brood is produced each year, but two may be possible in Mexico and Arizona. Look for adults in late spring through midsummer in woodlands, backyard gardens, and areas with wet soil.

Butterfly and Moth Anatomy
Antennae: Butterflies and Moths have a pair of antennae on the head used for sensing.
Head: The head is home to the insect's eyes, antennae, and proboscis.
Thorax: Home to the three pairs of legs as well as vital internal organs.
Abdomen: Contains vital internal organs such as the heart(s) and reproduction facilities.
Forewing: The upper, forward wing pair used for flying.
Hindwing: The lower, rearward wing pair used for flying.
NOTE: Butterflies and Moths are part of the Lepidopteran order as they share many similarities.
