detail

Incurvaria koerneriella: young larva

young larva

mine

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.

hostplants

Fagaceae, Malvaceae; nauw polyfaag

Fagus sylvatica; Quercus; Tilia.
