The family Saturniidae (order Lepidoptera), commonly known as saturniids, include the largest species of moths such as the giant silkmoths, royal moths and emperor moths. These moths are characterized by large size, heavy bodies covered in hair-like scales, lobed wings, reduced mouthparts and small heads, sometimes brightly colored and often with translucent eyespots on their wings. Together with certain Noctuidae (chiefly Calpinae and Catocalinae, such as the genera Ascalapha, Erebus or Thysania), the Saturniidae contain the largest Lepidoptera, and some of the largest insects alive today.

Class Insecta (Insects) Order Lepidoptera (Butterflies and Moths) Superfamily Bombycoidea (Silkworm, Sphinx, and Royal Moths) Family Sphingidae (Sphinx Moths) Other Common Names Hawk Moths (adults) Hornworms (larvae) Synonyms and other taxonomic changes Sphingidae Latreille, 1802 Explanation of Names Sphingidae from the type genus Sphinx (Linnaeus), for the Egyptian Sphinx. Common name “Hornworm” due to the stiff pointy dorsal extension near the end of the abdomen of most larvae. Numbers There are 124 described species found in America north of Mexico.(1) Size Wingspan 28-175 mm. Identification Adult - medium to very large. Body very robust; abdomen usually tapering to a sharp point. Wings usually narrow; forewing sharp-pointed or with an irregular outer margin. No ocelli or tympanal organs. Proboscis usually well developed, extremely long in some species that feed in flowers with deep calyxes. Antennae gradually thicken along length, then become narrower toward tip. Larva - naked except for a few scattered hairs. Most have a prominent dorsal horn at the tip of abdomen (thus the name, hornworms). Range Throughout North America. Season Year round in the south Food Larvae feed both day and night on many kinds of woody and herbaceous plants. Adults feed on nectar and some are important pollinators. Life Cycle Usually pupate in soil, though some form loose cocoons among leaf litter. Remarks Some are active only at night, others at twilight or dawn, and some, such as the clearwings (e.g. genus Hemaris - not to be confused with the Clearwing family, Sesiidae) feed on flower nectar during the day. Some larvae (hornworms) do serious damage to crop plants (e.g. tomato, tobacco, potato). Hornworms are often attacked by braconid wasp parasitoids.
