Family Saturniidae (Emperor and giant silk moths)

Saturniids or emperor, royal or giant silk moths is a relatively large family with around 2,300 species. The family contains some of the largest moth species in world.

Adults have large, lobed wings, heavy bodies covered in hair-like scales, and reduced mouthparts. Saturniids 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 have wingspans between 2.5–15.2 cm, but some tropical species such as the Atlas moth may have wingspans up to 30 cm. Together with certain Noctuidae, Saturniidae contains the largest moths and some of the largest extant insects.
