When threatened, the elephant hawk-moth caterpillar mimics a snake by puffing up and displaying large eyespots to scare off predators.

Every July, nature enthusiasts gather for National Moth Week to celebrate the beauty and diversity of moths. 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 and white body—can be found across North America. Its caterpillars are also green and known for their impressive size, as well as their ability to emit clicking sounds and regurgitate intestinal contents as a defense mechanism against predators.

National Moth Week, held during the last full week of July, encourages communities to host 'mothing' events, where participants use light or bait to attract moths for observation and data collection. This citizen science initiative began in 2012 in central New Jersey and has since expanded to over 90 countries, engaging people in the fascinating world of moths. With their incredible diversity and ecological importance, moths play crucial roles in pollination and serve as a vital food source for other wildlife.

So the next time you leave a light on during a balmy summer night, keep an eye out—one of these nocturnal visitors might just flutter by.
