The monarch’s scientific name is Danaus plexippus.

Butterflies and moths belong to a category of insects called Lepidoptera, which means “scale wing.” It comes from the Greek word s lepidos (scale) and pteron (wing). Monarch wings are made of thousands of tiny overlapping scales, like fish scales or shingles on a roof. These powdery scales give butterflies their beautiful color and patterns.
