io moth
Quick Summary
The Io moth (Automeris io) is a North American saturniid moth known for the large, circular, eyelike spots on its hindwings. Saturniid moths, in general, are a family of about 3,400 species characterized by stout bodies, broad wings often with vibrant colors and patterns, and typically a central eyespot on each wing.12
Adult saturniids often have reduced mouthparts and do not feed, living only a short time to reproduce. Males use feathery antennae to detect female pheromones. The larvae, or caterpillars, are typically green and feed on foliage. The Io moth caterpillar is bright green with red and white stripes and possesses stinging spines that can irritate skin.23
