In the larval stage, a moth or butterfly (typically a caterpillar) has mandibles and a conventional mouth to feed on plant material (or, rarely, on insects). As an adult, most species of butterfly have a curled tube called a proboscis that extends to drink nectar from flowering plants. Some get nutrients from pollen, decaying matter, or wet soil. Some adult butterflies do not eat at all, and have a very short lifespan.

The viceroy butterfly has evolved to mimic the monarch butterfly to avoid being eaten by birds that have previously tried eating a monarch butterfly.
