Lepidopterans are insects belonging to the order Lepidoptera, which includes butterflies and moths. They are characterized by their large, often colorful wings covered in tiny scales. These insects undergo a complete metamorphosis, transitioning from egg to larva (caterpillar), then to pupa (chrysalis or cocoon), and finally to adult. Lepidopterans play essential roles in ecosystems as pollinators and as a food source for other animals. They are found in various habitats worldwide, from forests to grasslands. Their diverse species exhibit a wide range of behaviors, colors, and sizes, making them a fascinating group for study and observation.
