  3. Insects and People Complete Metamorphosis Order Coleopterabeetles • Complete metamorphosis • Largest order of insects (most species) • Immatures and adults have chewing mouthparts. • Forewings hardened structures called elytra • Feeding habits are varied. Some are serious pests, others are beneficial.
