The largest butterfly in the world is the Alexander bird-winged butterfly with a wingspan of 31 meters, while the smallest butterfly in the world is the small gray butterfly, which generally has a wingspan of 16 mm. In 1983, a Chinese entomologist collected a small gray butterfly with a wingspan of only 13 mm in the original forest of Xishuang, Yunnan, creating a record for the smallest butterfly in the world.

Adults of the little gray butterfly mainly suck on nectar, while the larvae nibble on a variety of plants, including tender shoots and fruits. During the breeding season, female butterflies will stop directly on the plants that the larvae like to eat to lay eggs. In order to prevent the larvae from being preyed upon by small predators, some species of females will secrete honeydew to attract ants to feed, and ants will protect them from harm when they receive food gifts.
