Which statement is NOT a feature of Raphidioptera?

• A. Four membranous wings with venation
• B. Elongated prothorax
• C. Broad flat head
• D. Forewings with three submarginal cells in the forewing

Answer: (D)

Raphidioptera are known for a combination of wing structure and body form: four membranous wings with distinct venation, an elongated prothorax that gives a long neck, and a broad, flat head. The wings are slender and well-veined, which fits their predatory lifestyle. The prothorax’s length is a defining feature, creating that distinctive neck-like appearance, while the head remains broad and flat at the front. So, having four membranous wings with venation is a correct feature, and the elongated prothorax is also correct, as is the broad, flat head. The statement about forewings containing exactly three submarginal cells does not fit Raphidioptera because their forewing venation is more complex, with multiple small cells from a richer network of veins, not just three.
