Fly

Order of insects

A fly (pl. flies) is an insect of the order Diptera (from Ancient Greek δι- di- 'two' and πτερόν pteron 'wing'), named for the single pair of wings. The hindwings have evolved into halteres, organs that sense rotation, giving flies precise control of their flight. Diptera is a large order containing more than 150,000 species, including horse-flies, crane flies, hoverflies, mosquitoes and others.
