The Io moth (Automeris io) larva is a heavily-spined, stinging caterpillar frequently found on oak trees. They are not lethal, however the spines release painful venom when touched and are extremely effective at deterring predators. The adult (moth) is nocturnal, and can sometimes be found resting on the side of a building with its wings folded. At rest the moth appears plain, but the concealed underwings contain a substantial eye spot. Learn more about Florida's species of stinging and venomous caterpillars here
