Question: Do butterflies sleep?

Answer: Butterflies don't sleep like people do, but many species do take a rest in groups, a behavior called "roosting." Some may pause for just a night, while others roost for the entire winter season. Roosting together helps protect butterflies from predators and preserves energy for long migrations.
