Subfamily Ceratocampinae — The Royal Moths

Harris, 1833

Etymology

Ceratocampinae: Cerato is Greek for “horn” and camp for “caterpillar.” The words combine to mean “horned caterpillar.”

The suffix inae is standard taxonomic nomenclature to indicate that word pertains to a zoological subfamily.

Pronunciation

sur-rah-toe-kam-pye-nee

Overview

Known as the “royal moths,” Ceratocampinae is one of eight or nine subfamilies within the family Saturniidae. Exclusive to the New World, Ceratocampinae vary between some of the smallest to some of the largest Saturniids.

Unlike their cousins, the Saturniinae, Ceratocampinae do not spin cocoons but instead pupate in underground chambers. The caterpillars contain hairs modified into horn-like appendages, and the antennae of adult males are quadripectinate for the first 1/2–2/3rds of their length and then filiform to the tip. Female antennae are filiform throughout.

Indiana’s Ceratocampinae caterpillars range from being oligophagous (Sphingicampa) to polyphagous. Adults lack a digestive system, do not eat, and exist solely for reproduction.
