Unlike most butterflies this species lays as many as twenty or thirty eggs on one leaf, in parallel rows, with equal intervals, and the larvae continue in some measure gregarious to the last, so that a large number of pupae are often found, at a little distance from each other, on a wall, or the trunk of a tree."
A diferenza da maioría de bolboretas esta especie deixa até vinte ou trinta ovos nunha folla, en filas paralelas, a intervalos iguais, e as larvas continúan de certo xeito gregarias até a fin, podéndose encontrar moitas crisálides xuntas, con pequena distancias un das outras, nunha parede, ou no tronco dunha árbore."
