A moth is an insect closely related to butterflies, belonging to the order Lepidoptera. Moths are typically nocturnal, meaning they are most active at night. They have a wide variety of sizes, colors, and patterns, which help them blend into their surroundings and avoid predators. Moths are attracted to light, which is why you often see them fluttering around porch lights. Moths undergo a complete metamorphosis, starting as eggs, then developing into larvae known as caterpillars, followed by a pupal stage before emerging as adults. Many species of moths play important roles in ecosystems, such as pollinating flowers and serving as food for other animals, including birds and bats.
