Frequently Asked Questions
The adult moth is harmless. However, its caterpillar has stinging hairs that can cause a painful rash if touched.
They are native to North America, ranging from the eastern United States to parts of Canada and Mexico.
It refers to Io, a priestess of Hera in Greek mythology who was transformed into a heifer—a classical reference common in scientific naming.
While possible for experienced breeders, it is not common. Their caterpillars have specific host plant requirements, and their stinging hairs pose a handling risk.
