Fly
Nematocera (includes Eudiptera)
Brachycera
True flies are insects of the order Diptera (from the Greek di = two, and ptera = wings). Their most obvious distinction from other orders of insects is that a typical fly possesses a pair of flight wings on the mesothorax and a pair of halteres, derived from the hind wings, on the metathorax. (Some species of flies are exceptional in that they are secondarily flightless). The only other order of insects bearing two true, functional wings plus any form of halteres are the Strepsiptera, and in contrast to the flies, the Strepsiptera bear their halteres on the mesothorax and their flight wings on the metathorax.

Famous quotes containing the word fly:
“The air deals blows: surely too hard, too often?
No: it is bent on bringing summer down.
Dead leaves desert in thousands, outwards, upwards,
Numerous as birds; but the birds fly away....”
—Philip Larkin (1922–1986)
“With as little a web as this will I ensnare as great a fly as Cassio.”

“Come away, come away, death,
And in sad cypress let me be laid.
Fly away, fly away, breath,
I am slain by a fair cruel maid.”
