Which insect is NOT in the order Coleoptera?

Explanation:
Beetles share a defining trait: their forewings are hardened into protective covers called elytra that shield the hind wings and abdomen, and they undergo complete metamorphosis. The insects listed as beetles (alfalfa weevil, bean leaf beetle, and bark/tree borers) all fit that pattern and belong to Coleoptera. The American cockroach is not a beetle; it belongs to the order Blattodea. Cockroaches have more flexible, membranous wings (or none at all) and a body plan that reflects a different type of development (incomplete metamorphosis). So the insect not in Coleoptera is the American cockroach.
