Heliconius butterfly in South America.
The moth family that includes both the largest individual moths and various silkworm moths is Saturniidae (commonly known as the giant silkworm moths).123
Members of this family are characterized by their stout, hairy bodies and broad, often vividly patterned wings. This group contains some of the largest insects known, such as the hercules moth (Coscinocera hercules) and the atlas moth (Attacus atlas). Additionally, several species within the family are economically significant for their ability to spin thick, silken cocoons, which are harvested to produce various types of commercial silk.13
