蛾 (é) is the Chinese word for "moth," which refers to a group of insects closely related to butterflies. Moths are typically nocturnal and are attracted to light. They have a wide variety of sizes, colors, and patterns, with some species being quite large and others very small. Moths play important roles in ecosystems, such as pollination and serving as food for other animals. Moths belong to the order Lepidoptera, which also includes butterflies. They have a unique life cycle that includes four stages: egg, larva (caterpillar), pupa, and adult. Many moths are known for their distinctive wing shapes and textures, which can help them camouflage against predators.
