A moth is an insect belonging to the order Lepidoptera, which also includes 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 undergo a complete metamorphosis, developing from eggs to larvae (caterpillars), then to pupae, and finally emerging as adult moths. Moths play important roles in ecosystems, such as pollination and serving as food for other animals. Some species, like the Luna moth, are known for their striking appearance, while others, like the clothes moth, can be pests that damage fabrics.
