Females lay their eggs on the leaves of host plants, and the larvae hatch and feed on the foliage. The larvae grow through several stages, shedding their skin each time before pupating on the ground. The adults emerge in the summer and mate, after which females lay their eggs, and the cycle begins again. The Io Moth is also known for its stinging spines, which can cause a painful rash if handled.
