  promethea moths, silkmoths

  Callosamia is a genus of large silkmoths in the family Saturniidae, first described by Alpheus Spring Packard in 1864. The genus contains three North American species: C. promethea, C. angulifera, and C. securifera. These moths are notable for their striking appearance, strong host plant associations with woody plants, and distinct behavioral differences including diurnal versus nocturnal mating activity that contributes to reproductive isolation between sibling species.
