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 15 cm (6 inches). 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.
