And then there's the insects' mighty power of metamorphosis. This trait not only transforms insects, but also helps them maximize the available resources in an ecosystem. Take butterflies. In their larval caterpillar form, they chomp hungrily through leaves at a rapid rate to help them grow and spin cocoons. But when they emerge as butterflies, these insects feed only on flower nectar. Metamorphosis means the larvae and adults of one species will never compete for the same resource, so they successfully share an ecological niche without limiting their own success. This process is so efficient that an incredible 86% of insect species undergo complete metamorphosis.
