The insect order that comprises House Flies and Mosquitoes is called?

The correct answer is the order Diptera. This order is characterized by insects that possess a single pair of functional wings, which differentiates them from other insect groups. In the case of house flies and mosquitoes, both are well-known examples within this order, exhibiting the distinct traits that define Diptera, such as having their hind wings modified into stabilizers called halteres, which help with balance during flight.

The order Lepidoptera, known for butterflies and moths, is recognized for its scaled wings, while Hemiptera includes insects such as true bugs that have a different mouthpart structure suited for piercing and sucking. Orthoptera comprises grasshoppers and crickets, insects that are typically characterized by their jumping ability and sound production. Each of these orders features distinct biological and anatomical traits that help classify insects accordingly, making Diptera the appropriate choice for house flies and mosquitoes.
