Incurvaria koerneriella: mines on Fagus sylvatica


Incurvaria koerneriella: young larva

young larva


The larvae start by making small, roundish blotch mines, often a considerable number in a single leaf. After some time they make a circular excision, not much smaller than the mine itself (3-4 mm in diameter). Thus sandwiched they drop to the ground, and there continue feeding on dead leaf material; all the while enlarging their case when needed.

host plants

Fagaceae, Malvaceae; narrowly polyphagous

Fagus sylvatica; Quercus; Tilia.

Beech seems the most important hostplant.


Mining larvae are found in May-June (Hering, 1957a).


BE recorded. (Phegea, 2011).

NE waargenomen (Kuchlein & de Vos, 1999a;, 2010).

LUX not recorded (Fauna Europaea, 2011).
