Actias luna is a common species in Canada and the USA, but is rarely encountered because of their short adult lifespan and the fact that most moths are nocturnal. This moth is found in the eastern half of the USA, and in Canada, ranges from Nova Scotia to the most eastern parts of Alberta. Although widely distributed, it is never extremely common in any particular area to be considered a pest. Most silkmoths have many natural predators and parasites which keep their populations in check. Only about 1% of all the eggs produced by a female make it to adulthood to further the next generation. In the north, this moth only has a single generation per year. Around NY and NJ, the climate is sufficient that one can find 2 generations per year.
