Description
A stout fly with a small head (10-14 mm in length).[9] The tergites are black, without the dust spots or blue-purple sheen of other Merodon species. The thorax and abdomen are hidden by dense, long, erect hairs of variable colouration. Tibia 3 of the male has 2 spurs at the apex.[10] The larva is described and figured by Hodson (1932) [11] and it is illustrated in colour by Rotheray (1993).[12]

Biology
They inhabit open areas in deciduous forest up into the subalpine zone but significantly synanthropic, occurring in suburban parks and gardens and on horticultural land.[13] The adult flies low in April to July with a fast zig-zag flight, among ground vegetation frequently settling on bare ground. Adult M. equestris feed on pollen and nectar. They visit a large variety of flowers for nectar,[14] while the larvae feed internally in tissues of bulbs of Amaryllidaceae, and they are regarded as a horticultural pest, especially of Narcissus. Females lay 1 egg at a time on leaves of this plant (or in soil by it). Larvae overwinter in the bulbs.[9] A bibliography of the literature on the biology of M. equestris is given by Barkemeyer (1994).[15]
