Why do moths fly toward lights?

Answer: They navigate by moon angle

They navigate by moon angle ✓ — Correct! Moths evolved to navigate using moonlight, keeping it at a constant angle. Artificial lights confuse this system—moths spiral toward bulbs trying to maintain their angle to what they think is the moon!

Light gives them energy — Wrong. Moths don't get energy from light like plants do. They eat as caterpillars and some adults don't eat at all.

They think it's the sun — Wrong. Moths are nocturnal and avoid sunlight. They're drawn to artificial lights due to confusion with their moon-based navigation system.
