Fenella arenariae Zombori, 1978

Hymenoptera, Tenthredinidae

mine

Small corridor, rather abruptly widening in an irregular, full depth blotch. Frass (to judge by Zombori’s drawing) in rather fine granules that, as is the rule in sawflies, lie loose in the mine, not unlike coarsley ground pepper. Pupation external.

hostplants

Rosaceae, narrowly monophagous

Potentilla cinerea (= arenaria).

phenology

Larvae are observed in June.

distribution within Europe

Hungary (Fauna Europaea, 2010).

larva

See Zombori (1978a). Contrary to Fenella nigrita the legs end in a large claw. Also the brown spot ventrally on abdomen 1 seems to be absent.
