Luna moth is fat and hairy. The edge of its hind wing is gray white and has a long curved "tail". Luna moth's body presents a terrible green, and each wing has a bright eye point, which is very beneficial for them to escape the enemy.
Luna moth has no mouth after breaking out of its cocoon, can't eat and drink, and can only starve. Their life span is only one week. Finding heterosexual mating and spawning in these short days is all their task. This moth often lays eggs on a variety of trees such as hickory and walnut, and usually breeds two generations a year.
