What is the difference between butterfly and bat?

Butterflies and bats are fundamentally different in several key aspects. Butterflies are insects belonging to the order Lepidoptera, characterized by their colorful wings and a life cycle that includes stages of egg, larva (caterpillar), pupa, and adult. In contrast, bats are mammals from the order Chiroptera, known for their ability to fly using wings formed from a membrane stretched between elongated fingers. Additionally, butterflies primarily feed on nectar, while bats may consume insects, fruits, or nectar, depending on the species.
