Family Saturniidae- The Giant Silkworm Moths
Saturniidae is a large family of moths with roughly 2300 known species. Adult saturniids can be easily recognized by their large, hairy bodies and relatively small heads. Adults of this group have reduced mouthparts and do not eat. They instead live off of the fat that they stored up as a larva. Because of this they are able to devote almost all of their time to reproduction. The adult males have very large, feathery antennae that allow them to detect the pheromones of a female from great distances.
