Explanation:

Only the invertebrate class known as insects have developed wings and flight. Approximately 350–400 million years ago, during the Carboniferous period, insects became the first creatures to develop flight. The appendages on the sides of pre-existing limbs, which already contained nerves, joints, and muscles employed for different reasons, may have developed into wings. These may have first been employed for gliding or for slowing the pace of descent when sailing.

Not all insects have the ability to fly. While more primitive insects like silverfish never developed wings, a handful of apterous insects have secondarily lost their wings. Only the late reproductive castes of some eusocial insects, such as ants and termites, acquire wings during the mating season before discarding them after mating, whereas individuals of other castes live their whole lives without wings.
