Why are butterflies so colourful?

Some butterflies perform mimicry with large spots resembling eyes that are startling enough to scare away birds. These ‘eyespots’ help butterflies avoid becoming bird food, and so over time have become bigger and brighter.

Their exquisite wing patterns also help communicate with other butterflies. Moths don’t need to be brightly coloured because they are nocturnal, but as butterflies are active in the day their colouration tells others about their quality as a potential mate.

Butterflies even use their impressive wings to control their temperature! By lining up with the sun and opening their wings they can absorb heat to warm up on cold days, and fold their wings up to cool down.
