Distribution:

I. koerneriella has been recorded so far from Spain throughout central Europa and Italy to Hungary and Romania. In Scandinavia, the species is known only from Sweden (Karsholt & Nieukerken, 2004). Only few data are available about the vertical distribution. Specimens have been found from the colline level to at least 1700 m a.s.l. (Kurz et al., 2009).

Biology:

The species inhabits open forests with significant portions of beech (Fagus sylvatica). The imagines are on the wing in April and May (Kurz et al., 2009).

Stages in development:

Larva. The larva is translucent, dirty whitish. The head is yellowish brown, on the dorsum of segments III and IV, a yellowish brown, transverse spot is found. When young, at the beginning of June, the larva mines leaves of Fagus sylvatica and Tilia-species, later it lives in a big, yellowish brown case on the ground, which is built from 3-4 pieces of leaves (Meeß 1910).
