 Like most species in its family, the caterpillars acquire chemical defenses from their host plants, so they are potentially toxic or unpalatable, but there is evidence that this species may also be venomous, though no venom has yet been isolated or identified.The behaviour and aposematic coloration of the larvae suggests chemical protection in this stage, although they have not been analyzed for alkaloid or cardenolide content, nor have the adults.There is one generation per year.
