Cytisus scoparius, Bergen NH


Hooklike, upper-surface corridor. The corridor begins near the base of a leaflet, runs along the margin to the tip, then, quickly widening, redescends over the midrib towards the base of the leaflet. Frass in the corridor part in fine grains, further up in smal clumps. Pupation outside the mine. Older mines turn black, and then are somewhat easier to find.


Fabaceae, oligophagous

Cytisus hirsutus, scoparius; Genista; Spartium junceum; Ulex europaeus.

Occasionally on Lupinus.


Larvae between April and September (Hering, 1957a).


BE recorded (Ellis: La Calamine).

NE recorded (de Meijere, 1924a).

LUX recorded (Ellis: Kautenbach).

distribution within Europe

From Scandinavia to the Iberian Peninsula and Italy, and from the British Isles to the Baltic States and Poland (Fauna Europaea, 2007); Bulgaria (Buhr, 1941b), Slovenia (Maček, 1999a).



De Meijere described the species from the Dutch localities Bussum and Hilversum; moreover he used mine material on Cytisus from Zeist, Vollenhove and Winterswijk. Johanna was his wife.
