Leaf-mine: An initially linear leaf-mine, normally adjoining leaf-margin and running towards apex of leaf, then turning and widening into a blotch in the area of the mid-rib (Spencer, 1972b: 40, fig. 123; Spencer, 1976: 117, fig. 190). The mine is illustrated in British leafminers and Nederlandse bladmineerders. Mine of Agromyza johannae on Cytisus scoparius. Image: Willem Ellis (Source: Nederlandse bladmineerders) Larva: The larva is described by Allen (1958), Dempewolf (2001: 57), de Meijere (1925) and in Nederlandse bladmineerders. Puparium: Reddish-orange; posterior spiracles each with 3 bulbs (Spencer, 1976: 117).

Time of year - adults: Unknown. Distribution in Britain: Common in gardens in Britain where Cytisus is frequently cultivated (Spencer, 1976) including London (Hampstead), Herts (Barnet), Surrey (Headley) (Spencer, 1972b: 42), Warwick (Keresley) (Robbins, 1991: 42), Inverness (Aviemore) (Spencer, 1972b: 42), Rum (Bland in Whiteley, 1994) and Hants (Fleet) (British leafminers) and Northern Ireland: Belfast (Spencer, 1972b: 42). Distribution elsewhere: Widespread in western Europe, including Denmark, Norway and Sweden (Spencer, 1976: 117), The Netherlands, Belgium and Luxembourg (Nederlandse bladmineerders), Germany (Spencer, 1976: 546; Dempewolf, 2001: 57), Crete, Czech Republic, Dodecanese Is., Estonia, French mainland, Italian mainland, Lithuana, Poland and Sicily (Martinez in Fauna Europaea).
