Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Certain families of the order Diptera (true flies) have specialized biological habits, such as inducing abnormal plant growths called galls.

Step 2: Detailed Explanation:
The gall midges or gall flies are grouped under the family Cecidomyiidae.
Their larvae feed on plant tissues and secrete substances (such as auxins) that induce the plant to form highly organized galls, which provide food and protection to the developing larvae.
An important agricultural example is the Rice Gall Midge, Orseolia oryzae.

Step 3: Final Answer:
Gall flies are grouped under Cecidomyiidae, which corresponds to option (D).
