North American Luna Moth

Actias luna

Also known as American Moon Moth

Luna moths emerge from silken cocoons at dusk equipped with striking lime-green wings and long trailing tails designed to disorient bat echolocation. Adults lack functional mouthparts or a digestive system, living for only about a week entirely on stored energy while searching for mates. Females release powerful pheromones that males detect from miles away using their large, feathery antennae.

Responsible observation
  • Porch Lights: Look for adults resting near outdoor white light sources during warm spring and summer nights.
  • Disturbance Avoidance: Observe gently without touching, as fragile wing scales rub off easily when handled.
  • Host Plants: Inspect sweetgum, hickory, or birch foliage in summer to spot the plump green caterpillars.
