The Luna moth is the largest in North America. They are precious because they are rarely seen. Their name comes from the circular shape on their wings. They only live for 7-10 days, and they don’t eat. They don’t even have a mouth. They live on the fat they acquire from their cocoons. They lay approximately 200 eggs that hatch in one week. We were blessed to see two nights of courting, and then we saw the mating of two moths.
