Which stage in complete metamorphosis normally causes the most damage by feeding?

• A. Egg
• B. Pupa
• C. Larva
• D. Adult

Answer: (C)

In complete metamorphosis, the larval stage is the primary feeding stage and typically causes the most damage. Larvae are built for rapid growth and have chewing mouthparts and a large gut, allowing them to consume substantial amounts of food—whether foliage, roots, or other materials—over an extended period and through many molts. The pupal stage is a non-feeding, resting period where the body is reorganized, eggs don’t feed, and adults usually feed little or not at all and focus on reproduction and dispersal. So the larva does the heavy lifting in terms of feeding and damage.
