Etainia albibimaculella (Larsen, 1927)

mine

The larva makes a slender gallery that eventually enters a petiole, from where it enters a bud. The larva hibernates in the bud, that is eaten out in spring. Then the larva bores in a young shoot, sometimes making an excursion into a leaf that then is completely mined out. Pupation in a dark yellow cocoon in the mine.
