What are the hardened forewings found in Coleoptera called?

• A. Hemelytra
• B. Elytra
• C. Tegmina
• D. Halteres

Answer: (B)

Beetles have hardened forewings called elytra. These elytra are thickened, protective covers that meet along the midline of the back and shield the delicate hind wings and the abdomen when the insect is at rest. When flight is needed, the elytra stay in place as the hind wings underneath unfold and operate for flight. This protective role and the specific presence of elytra are characteristic of Coleoptera. Other terms refer to forewings in different insect groups. Hemelytra belong to true bugs (like cicadas and aphids) and have a partly hardened base with a membranous tip. Tegmina are leathery forewings found in orthopterans (such as grasshoppers and cockroaches). Halteres are not wings at all—they’re small balancing organs in flies.
