I have recently obtained this elegant Phalenid from its larva, which feeds on the wild red cherry (Prunus Pennsylvanica). July 8, several nearly mature caterpillars were discovered on the twigs of their foodplant. They were an inch in length; color dull red, closely simulating the bark of the branches; and to more effectually conceal themselves by mimicry, they hold on, when at rest, by their pro-legs only, the body standing out like a short branch, or they hold to a leaf by their fore legs, making their bodies appear like a petiole.
