Luna moth

Featured in today's image is the luna moth, a species whose charm rivals that of butterflies. Also known as the American moon moth, this striking insect—with its lime-green wings, white body and moon-like eyespots—can be found across North America. Its caterpillars are also green and are known for their impressive size, as well as their ability to emit clicking sounds and regurgitate intestinal contents as a defence mechanism against predators.

The luna moth's life cycle spans about 7 to 8 weeks, beginning when a female lay 200-400 eggs, singly or in small groups, on the underside of leaves. Its life unfolds in distinct stages—around 10 days as eggs, 6-7 weeks as larvae, 2-3 weeks as pupae and about 7-10 days as adults. Adult luna moths have only vestigial mouthparts and no functioning digestive system, so they do not eat; instead, they survive solely on the energy stored during their caterpillar stage. Even though they only stick around for a short time, luna moths manage to leave a lasting impression—like a quiet reminder of how magical nature can be.
