Luna moth
The luna moth is a large North American moth in the family Saturniidae, with the scientific name *Actias luna*.
The luna moth is a large, pale green North American moth known for its long hindwing tails and very short adult lifespan of about one week.
What it is
The luna moth (*Actias luna*) belongs to the giant silk moth family Saturniidae. Adults have pale green wings, a white body, and curved tails on the hindwings with eyespots that help confuse predators. They are nocturnal and do not feed as adults, lacking a functional mouth or digestive system.
Life cycle and habitat
Luna moths undergo complete metamorphosis from egg to caterpillar, pupa, and adult. Caterpillars feed on leaves of walnut, hickory, sweet gum, and birch trees. The species is native to eastern North America, including parts of southern Canada, and is found in or near deciduous woodlands.
Why it matters
As a native insect, the luna moth plays a role in woodland ecosystems. Its brief adult stage and distinctive appearance make it a familiar species for Canadian nature enthusiasts. The moth is not listed as threatened, but its presence indicates healthy deciduous forest habitats.
