The largest type of butterfly in the world is the Atlas moth (Attacus atlas). Native to the tropical and subtropical forests of Southeast Asia, the Atlas moth is renowned for its impressive wingspan, which can reach up to 30 centimeters (about 12 inches). Its wings display striking patterns and colors that serve as camouflage against predators, making them one of the most visually stunning insects. The Atlas moth is primarily nocturnal and feeds on the nectar of flowers, although it does not eat in its adult stage. Their sheer size and beauty make them a fascinating subject of study.
