Polyphemus Moth

Antheraea polyphemus, the Polyphemus moth, is a North American member of the family Saturniidae, the giant silk moths. It is a tan-colored moth, with an average wingspan of 15 cm (6 in). The most noticeable feature of the moth is the large, purplish eyespot on each hindwing; its name is from the Greek myth of the cyclops Polyphemus. The species, first described by Pieter Cramer in 1776, is widespread in continental North America, with local populations found throughout subarctic Canada and in all of the United States except Arizona and Nevada.

Polyphemus moths inhabit deciduous hardwood forests, orchards, urban areas, and wetlands. The caterpillar can eat a total of 86,000 times its weight in the first eight weeks after it emerges. Polyphemus moths are considered to be very polyphagous, meaning they eat from a wide variety of plants.
