The fly is not the smallest of winged things, on a level with gnats, midges, and still tinier creatures; it is as much larger than they as smaller than the bee. It has not feathers of the usual sort, is not fledged all over like some, nor provided with quill-feathers like other birds, but resembles locusts, grasshoppers, and bees in being gauze-winged, this sort of wing being as much more delicate than the ordinary as Indian fabrics are lighter and softer than Greek. Moreover, close inspection of them when spread out and moving in the sun will show them to be peacock-hued.

 Its flight is accompanied neither by the incessant wing-beat of the bat, the jump of the locust, nor the buzz of the wasp, but carries it easily in any direction. It has the further merit of a music neither sullen as with the gnat kind, deep as with the bee, nor grim and threatening as with the wasp; it is as

 

much more tuneful than they as the flute is sweeter than trumpet or cymbals.
