To which order do non-biting flies belong?

Non-biting flies belong to the order Diptera. This order is characterized by insects that have just one pair of functional wings, while the hindwings are reduced to structures called halteres, which help with balance and stability during flight. Diptera includes a wide variety of flies, including houseflies, fruit flies, and many others that do not bite or feed on blood.

The other options represent different orders of insects with distinct characteristics: Coleoptera includes beetles, which have hard, protective wing covers; Hymenoptera encompasses wasps, bees, and ants, often with complex social structures; and Lepidoptera includes butterflies and moths, recognized by their scaled wings. Understanding these classifications helps in identifying pest species and their behaviors, which is crucial in pest control practices.
