Beetles make up the largest insect order, with hundreds of thousands of named species.

The longer version

Beetles dominate the insect world partly because their forewings hardened into tough covers that shield the abdomen and reduce water loss. That sturdy shell lets them squeeze into soil, bark, and stored food where softer animals would dry out or be crushed.

Their chewing mouthparts have been modified many times over, so different lineages exploit leaves, wood, grain, carrion, or other insects. Complete metamorphosis helps too: larvae and adults often eat different things, keeping the two stages from competing for the same resources. Wide variation in body shape reflects how many separate ways of living they have taken up.
