Question

The nature of hind wings in beetles is:

• A. Elytra
• B. Hemelytra
• C. Membraneouse
• D. Tegmen

Hint:

Beetle Wing modifications:
- Forewing: Elytra (thickened, hard, protective).
- Hindwing: Membranous (used for flight, folded under elytra).

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
The modification of wings in different insect orders represents specialized evolutionary adaptations for flight efficiency and protection.

Step 2: Detailed Explanation:
In the order Coleoptera (beetles), the forewings are modified into hard, heavily sclerotized, veinless protective covers called elytra.
The hind wings, which are used actively for flight, remain fully membranous (spelled as "Membraneouse" due to a typographical error in the paper).
When the beetle is at rest, these membranous hind wings are folded lengthwise and crosswise beneath the protective elytra.

Step 3: Final Answer:
The nature of hind wings in beetles is membranous, which corresponds to option (C).
