same mine, detail

mine

Yellowish primary blotch, almost invariably lower-surface. Pupation generally outside the mine; less often the puparium is formed in the opening, sometimes even in the closed mine. The exit slit (when made by the larva) has a characteristic shape: a perfect semi-circle.

hostplants

Salicaceae, monophagous

Salix alba, aurita, caprea, cinerea, fragilis, myrsinifolia, pentandra, purpurea, triandra, viminalis.

A. o. Hering (1925a), Buhr (1932a), Haase (1942a), Kabos (1971a) and Nowakowski (1954a) report tridentata from Populus species, but that is due to confusion with other Aulagromyza species.

phenology

Larvae in June-July and September (Hering, 1957a).

BENELUX

BE recorded (De Bruyn & von Tschirnhaus, 1991a).

NE recorded (van der Wulp, 1871a; de Meijere, 1924a, 1939a).

LUX not recorded (Fauna Europaea, 2007).

From Scandinavia to France and Italy, and from England to the Baltic States and Poland (Fauna Europaea, 2007).

synonyms

notes

Mines of A. tridentata can easily be confused with young tentiform mines of Phyllonorycter species.
