The Saturniidae, commonly known as saturniids, are among the largest and most spectacular of the moths. They form a family of Lepidoptera, with an estimated 2,300 described species worldwide.[1] The Saturniidae include such Lepidoptera as the giant silkmoths, royal moths and emperor moths.
Adults are characterized by large size, heavy bodies covered in hair-like scales, lobed wings, reduced mouthparts, and small heads. They lack a frenulum but the hind wings overlap the forewings, producing the same effect of an unbroken wing surface.[2] These moths are sometimes brightly colored and often have translucent eyespots or "windows" on their wings. Sexual dimorphism varies by species, but males can generally be distinguished by their larger, broader antennae. Most adults possess wingspans between 1 to 6 inches (2.5 to 15 cm), but some tropical species, such as the Atlas Moth (Attacus atlas), may boast quite incredible wingspans of up to 12 inches (30 cm). Together with certain Noctuidae (chiefly Calpinae and Catocalinae, such as the genera Ascalapha, Erebus or Thysania), the Saturniidae thus contain the largest Lepidoptera, and indeed some of the very largest insects alive today.
