Callosamia promethia foodplants...

[Mothman617]

I have quite a bit of experience in rearing C. promethea. In fact it is one of
the easiest of the native Saturnids to breed. The best foodplants to start with
is either Sasafrass, Spicebush or Black Cherry (P. serotina). The female should
lay about 30 to 75 eggs and young larvae will emerge in about two weeks. During
the first few instars the foodplant must be changed daily. After 24 hrs the
leaves will become tough and dry.
