Which order consists of insects with incomplete metamorphosis?

Insects that undergo incomplete metamorphosis are characterized by three developmental stages: egg, nymph, and adult. The nymph stage resembles a smaller version of the adult and gradually matures into the full-sized adult without the distinct pupal stage seen in complete metamorphosis.

The correct conclusion is that none of the orders listed—Lepidoptera (butterflies and moths), Coleoptera (beetles), and Hymenoptera (wasps, bees, and ants)—exhibit incomplete metamorphosis, as all of these orders undergo complete metamorphosis, which includes the pupal stage. Therefore, the choice stating "None of the above" aptly captures the absence of any orders with incomplete metamorphosis among the provided options. Understanding the life cycles of different insect orders is crucial in pest control and management practices.
