Question

Insect hind wings are modified into knob-like structures called "halteres" in:

• A. Mustard sawfly
• B. Fruit fly
• C. Whitefly
• D. Damselfly

Hint:

Halteres:
- Modified hind wings in Diptera.
- Function as balance organs.
- Found in flies (e.g., fruit fly, housefly).

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
This question tests knowledge of insect wing modifications.

Step 2: Detailed Explanation:
Halteres are modified hind wings found in Diptera (flies).
Fruit fly (Drosophila melanogaster) has halteres.
Mustard sawfly (A): Hymenoptera (wings not modified).
Whitefly (C): Hemiptera (wings not modified).
Damselfly (D): Odonata (wings not modified).
Thus, halteres are found in fruit flies.

Step 3: Final Answer:
Thus, insect hind wings are modified into halteres in fruit flies, which corresponds to option (B).
