The Polyphemus moth (Antheraea polyphemus) is a North American member of the family Saturniidae, the giant silk moths. It is a tan colored moth, with an average wingspan of 6 inches (15 cm). The most notable feature of the moth is its large, purplish eyespots on its two hindwings. The eye spots are where it gets its name – from the Greek myth of the Cyclops Polyphemus. The caterpillar of the Polyphemus moth can eat 86,000 times its weight at emergence in a little less than two months. It is widespread throughout much of North America, from southern Canada to parts of Mexico.
