Question

Aquatic insect family Sisyridae belongs to order:

• A. Neuroptera
• B. Hemiptera
• C. Plecoptera
• D. Strepsiptera

Hint:

Spongillafly larvae have elongated mouthparts adapted for feeding on sponge tissues.

Answer 1

The Correct Option is A

Step 1: Rule out Hemiptera - its piercing-sucking mouthparts don't match sponge-chewing larvae.
Step 2: Rule out Plecoptera and Strepsiptera - different wing structure and lifestyle from Sisyridae.
Step 3: Sisyridae adults resemble lacewings and have chewing mouthparts, both hallmark Neuroptera traits.
Step 4: The correct option is Neuroptera.
