Quick answer
Luna Moths have a two-stage diet: caterpillars eat leaves, while adults do not feed, adjusting with season, age, and what is abundant in Deciduous forests of eastern North America. That label is a preferred pattern, not every item an individual might sample.

Luna Moth diet overview
Luna Moths (Actias luna) are best summarised as Caterpillars eat leaves; adults do not feed. Anatomy and habitat (Deciduous forests of eastern North America) decide whether they hunt, graze, filter, scavenge, or mix strategies across the year.
How luna moths find food
Energy-rich foods are prioritised when available; lean seasons force broader diets or longer travel. Young animals may eat different items or receive food from parents.
Luna Moth role in the food web
As consumers in their food web, luna moths move nutrients and influence prey or vegetation.
Feeding and human conflict
Never feed wild luna moths. Habituation raises injury risk and can lead to lethal management. Captive diets must match species needs, not generic pet food rules.
Appearance
The luna moth is among the most striking moths in North America, with broad, pale-green wings, eyespots, and long, twisting tails trailing from the hindwings. Its body is white and furry, and the antennae of males are large and feathery for detecting females. Its size and soft color make it unmistakable when it appears at lights on summer nights.
A brief adult life
Adult luna moths have no functional mouthparts and do not feed, living on energy stored during the caterpillar stage. As a result they survive only about a week, during which their sole purpose is to find a mate and reproduce. Females release pheromones to attract males, which locate them using their sensitive antennae.
