How many pairs of wings do wasps have?

Wasps are classified as insects belonging to the order Hymenoptera, which also includes bees and ants. Insects in this order typically have two pairs of wings. The forewings are larger and more robust, while the hindwings are smaller and often serve to aid in flight stability. This wing structure is characteristic of wasps and provides them with the ability to maneuver efficiently while flying.

The presence of one pair of wings is incorrect because that would describe some other insects, such as flies, which have evolved to have only a single pair of wings for flight, relying on other structures for balance. Three pairs or four pairs of wings do not align with the anatomical structure of wasps, as insects with such wing configurations are not representative of this group. Hence, the correct answer reflects the typical biological and evolutionary characteristics of wasps within their broader ecological context.
