Plant Parasites of Europe

leafminers, galls and fungi

Trachys fragariae

Trachys fragariae Brisout de Barneville, 1874


Upper-surface brownish primary blotch, without a preceding corridor. Frass in thread fragments. On top of the oviposition site, mostly at the leaf margin, a shining black drop of black secretion. Pupation in the mine (Hering, 1957a).

host plants

Rosaceae, oligophagous

Anserina reptans; Fragaria vesca, viridis; Potentilla argentea, recta, reptans; Rubus.

F. viridis is the main host plant (Hering, 1957a).


Larvae in July-August (Hering, 1957a).


BE not recorded (Fauna Europaea, 2007).

NE not in the Netherlands, although it occurs in nearby Germany (Brechtel & Kostenbader, 2002a). However, Bilý (2002a), Niehuis (2004a) and the Fauna Europaea (2007) do mention the species as Dutch. Given the ecology of the miner this does not seem very probable.

LUX not recorded (Fauna Europaea, 2007).

distribution within Europe

South of the line France, Germany, Ukraine (Fauna Europaea, 2007).
