Metallus pumilus mine

Rubus fruticosus, Arnhem, Sonsbeek


No visible egg; it is deposited below the upper epidermis, generally close to a major vein. From there begins a short, quickly widening corridor that contains much frass, especially in its first part. The corridor opens into a large, very transparant, almost full depth blotch that often overruns the initial corridor. Frass in loose grains, larger as the larva increases in size. The frass is dry, and in old mines it may accumulate like pepper grains in the lowest part. Larva solitary, belly-up in the mine; firsst abdominal segment ventrally with a brown or black spot, like also in thorax 2 and 3. Prepupa totally white.

host plants

Rosaceae, monophagous

Rubus caesius, fruticosus, idaeus, leptadenes, odoratus, phoenicolasius, radula, rhombifolius, sanctus, saxatilis, spectabilis, vulgaris.


Mines in June-July and September (van Frankenhuyzen & Freriks, 1972c).


BE recorded (Fauna Europaea, 2008).

NE recorded (van Ooststroom, 1976a); in most years a common species.

LUX recorded (Chevin, Ellis & Schneider, 2011a).

distribution within Europe

From Sweden and Finland to the Pyrenees, Italy and Roumania, and from Ireland to the Ukraine (Fauna Europaea, 2008). Also Greece (Standfuss ao).



Entodecta pumila.

parasitoids, predators

Achrysocharoides cilla; Pnigalio pectinicornis; Sympiesis sericeicornis.


The raspberry leaf-mining sawfly may also appear in greenhouse crops of blackberries and raspberries, and then cause considerable damage (Burger ao, 1985a).
