In complete metamorphosis, which statement best describes the relationship between larval and adult foods?

• A. Larvae and adults eat the same foods
• B. Adults feed the same foods as larvae in all species
• C. Adults and larvae typically feed on different foods or some adults do not feed
• D. Feeding patterns are identical to larval patterns

Answer: (C)

In complete metamorphosis, larval and adult stages are adapted to use different resources, reducing competition between life stages. Larvae are typically built for rapid growth and heavy feeding on one set of foods, while adults often have mouthparts and behaviors geared toward reproduction and dispersal, sometimes feeding on nectar or not feeding at all. This separation allows a wide range of species to exploit different ecological niches. For example, caterpillars usually eat leaves, while butterflies and moths may drink nectar as adults. Some insects, like certain mayflies, don’t feed at all as adults. Because of this distinct separation in diets or feeding activity between stages, the statement that adults and larvae typically feed on different foods or that some adults do not feed best captures the relationship.
