Fenella arenariae Zombori, 1978
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.
Rosaceae, narrowly monophagous
Potentilla cinerea (= arenaria).
Larvae are observed in June.
distribution within Europe
Hungary (Fauna Europaea, 2010).
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.
