Cecropia Moth with Cocoon - Hyalophora cecropia
I assume the moth emerged from the cocoon, but can't tell for sure because I couldn't see if the cocoon had split open.
I don't know what kind of tree/shrub this moth was on. There was a mating pair nearby.
Habitat: Vegetation along the Maine coast; They were in a garden next to a construction site.
The Cecropia Moth is North America's largest native moth. It is a member of the Saturniidae family, or giant silk moths. Females with a wingspan of six inches or more have been documented. It is found as far west as the Rocky Mountains and north into the majority of Canadian provinces. The larvae of these moths are most commonly found on maple trees, but they have been known to feed on cherry and birch trees among many others.
