A group of butterflies is officially called a kaleidoscope. Isn't that fun?! Sometimes they are referred to as a swarm. Groups of caterpillars are called an army.

At night, monarch butterflies gather in tree clusters. A cluster of butterflies is called a roost.
Why do monarchs roost? One hypothesis is that roosting behavior is an anti-predator strategy. Cool temperatures paralyze monarchs, making them vulnerable to predators. A roost provides safety in numbers. When overnight temperatures are warm, monarchs may not aggregate as tightly or roost at all. Perhaps monarchs shift to roosting behavior when cold overnight temperatures make them vulnerable.
