DESCRIPTION: Up to 4.5mm in length.  As with many species of Fruit-Fly the wing pattern is an essential in part of the ID process.  Combine this with the blackish-brown body that has a pale pruinesence on the surface, the rufous legs and head and the white face and black oviscape, the overall identification should be complete.  Males have dark femurs whilst females have yellow femurs.  The third antennal segment of the males is dark brown, that of the females is paler. BEHAVIOUR: Adults overwinter. The larvae live inside the flower head, feeding on the developing seeds. DISTRIBUTION: Fairly common throughout southern Britain but found further north too. HABITAT: Found in areas here Leucanthemum species grow, especially Ox-Eye Daisy. PERIOD: April to late summer.
