The adult male luna moths are easily distinguished from the females by their “bushier” antennae. These moths, surviving at the most for a week, never eat. After mating, females begin to lay eggs on suitable host plants, and continue doing so until their death one or two nights later. As soon as the females emerge, they begin releasing pheromones to attract the males, and will generally mate with the first male they encounter. The males, emerging first, disperse over great distances. Like most moths, they are strictly nocturnal.

When they find a suitable tree, they wrap themselves in leaves and spin cocoons. When the solitary caterpillars have matured to their fifth instar (moult), they begin to wander from their original host plant. However, in only three or four weeks, the caterpillars shed their skin five times, doubling their length about every week until they are 70 mm (2¾ in) long. After 7-10 days, the tiny caterpillars emerge from their eggs, able to sit at fullest extension upon the eraser of a pencil. Of the most common host plants-hickory, walnut, sweet-gum, persimmon, sumac, and birch-moths at MLBS most likely utilize hickory and birch. The eggs, smaller than the head of a pin, are white and faintly oval-shaped, coated in a brown adhesive to help them cling to the host plant.

This striking moth is, arguably, the most distinctive and beautiful in our area.
