A butterfly is an insect belonging to the order Lepidoptera, which also includes moths. Characterized by their colorful wings, butterflies undergo a complete metamorphosis, which consists of four stages: egg, larva (caterpillar), pupa (chrysalis), and adult. They are known for their unique life cycles and incredible migration patterns, such as the monarch butterfly's journey across North America. Butterflies primarily feed on nectar from flowers and play a vital role in pollination, helping to sustain various ecosystems. Their delicate beauty and ecological importance make them significant creatures in both nature and culture.
