CALLOSAMIA OF THE WORLD

CALLOSAMIA (PACKARD, 1864): Moths of this genus are very similar to Hyalophora and C. angulifera has been successfully crossed with both H. cecropia and S. cynthia. The three Callosamia species can also be crossed.

The genus is distinguished from the Hyalophora by Callosamia females having the pectinations of the anterior pair shorter than the posterior pair on each antennae joint.

In the larvae, abdominal segments 1 and 2 bear one scolus or none below the spiracle, or sometimes a second very rudimentary one. The scoli alpha of the first abdominal segment are not much larger than those of the second segment.
