Profenusa pygmaea mines

Quercus palustris, Putten, Schovenhorst; on this species the mines are unusually large, probably because the leaves are relatively thin.


Upper surface blotch, often rather narrow where it begins, but without a real preceding corridor. Frass in gradually larger grains scattered in the mine. Never more than one larva in a mine. Pupation outside the mine.

host plants

Fagaceae, oligophagous

? Castanea sativa; Quercus aliena, cerris, dalechampii, ithaburensis subsp. macrolepis, palustris, petraea, pubescens, robur, rubra.

Buhr (1941a) remarks that all mines on sweet chestnut were unfinished. That may indicate that Castanea is not the real host plant. I myself never found the mine on this tree.


Larvae in June – July (Hering, 1957a); one generation (Robbins, 1991a).


BE recorded (Fauna Europaea, 2008).

NE recorded (van Ooststroom, 1976a).

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

distribution within Europe

All of Europe, perhaps excluding the Balkan Peninsula (Fauna Europaea, 2008).



Fenusella pygmaea.
