Actually, the Ceanothus Moth is in the genus Samia, though even
intergeneric similarities in pheromones are reasonably common in the
saturniids. The likelihood of this cross-generic attraction is made
even more reasonable when one realizes that the Ceanothus Moth is an
import -- as Cecropia and Ceanothus moths would not have originally
been found together in nature, there would certainly have been no
possibility for confusion and no selection for different pheromonal
