Members of the suborder Athericera are sometimes referred to as the ‘higher’ flies (i.e. they are more highly evolved). They have short antennae comprising three segments, the two nearest to the head being very small, and the third comparatively large with a prominent bristle or arista (Fig. 7.1). Members of the Athericera vary considerably in size from 2 mm to over 10 mm and are the most specialized and numerous of the Diptera, being found in every part of the world. This suborder includes the hover flies, Syrphidae (Fig. 7.2), which are sometimes confused with the four-winged bees and wasps, and the fruit-flies (Drosophila) (Fig. 7.3) the larvae of which are often found infesting sugar-containing substances.
