"like an ambigous trope of hopefulness, the luna moth took wing "
The luna moth is a lime green moth with a wingspan of up to 11.5 cm, making it one of the largest moths in North America. Adult moths emerge from their cocoons in the morning. Their wings are very small when they first emerge and they must enlarge them by pumping bodily fluids through them. During this time, their wings are soft, and they must climb somewhere safe to wait for their wings to harden before they can fly away. Adult luna moths live for only a week, and are thus rarely seen, despite being fairly common.
