Actias luna

The luna moth (Actias luna) is a lime-green, Nearctic Saturniid moth in the family Saturniidae, subfamily Saturniinae. It has a wingspan of up to 114 mm (4.5 in), making it one of the largest moths in North America.

Distribution

This moth is found in North America from east of the Great Plains in the United States to northern Mexico and from Saskatchewan eastward through central Quebec to Nova Scotia in Canada. There have been sightings as far south as central Florida. See map.

Life cycle

Based on the climate in which they live, the luna moths produce differing numbers of generations. In Canada and northern regions, they can live up to 7 days and will produce only one generation per year. These reach adulthood from early June to early July. In the northeastern United States around New Jersey or New York, the moths produce two generations each year. The first of these appear in April and May, and the second group can be seen approximately nine to eleven weeks later. In the southern United States, there can be as many as three generations. These are spaced every eight to ten weeks beginning in March.
