The larvae that are flat and elongate belong to which order?

• A. Lepidoptera
• B. Siphonaptera
• C. Raphidioptera
• D. Coleoptera

Answer: (C)

Larval form often reflects how the insect lives and feeds. Long, slender, and often flattened larvae are a hallmark of certain neuropteroid predators that hide in tight spaces like under bark or in leaf litter. The larvae of the group in question are classic examples: they’re elongated and have legs, built to move through narrow crevices to hunt prey. This matches snakeflies, the order Raphidioptera, whose larval stage is long and slender and well-suited for living in crevices. In contrast, Lepidoptera larvae are caterpillars that are typically more cylindrical with prolegs; Siphonaptera larvae are legless maggots living in dust or plant debris; Coleoptera larvae come in various forms, but many are grub-like and not the same elongated, flattened shape. So the flat, elongate larva described fits Raphidioptera.
