Relative of a butterfly

MOTH

This nocturnal insect is often drawn to lights at night and has a fuzzy, less colorful appearance than its daytime cousin.

A moth is a close relative of a butterfly, sharing the same insect order (Lepidoptera) but typically active at night. The clue plays on their biological connection—both have wings and undergo metamorphosis, though moths are often less colorful. It’s a straightforward definition with no hidden wordplay, just a simple fact about nature.
