True or False: Mosquitoes belong to the order Diptera and possess two pairs of wings.

Mosquitoes belong to the order Diptera, which is characterized by having only one pair of wings. Insects in this order, commonly known as true flies, have evolved to possess only a single pair of functioning wings, while the second pair has been modified into small, balancing structures called halteres. These halteres assist with flight stability and maneuverability. Therefore, the assertion that mosquitoes have two pairs of wings is incorrect, making the correct answer false.

The related options that suggest dependence on species or environmental variation do not apply here since all mosquitoes uniformly share the characteristic of having only one pair of wings within their classification.
