Found new for Belgium in 1999 in NA. Hitherto a very rare and seldom recorded species.
It makes characteristic mines in the stem of the food plant. The larva makes a fairly long (up to 9 cm) gallery in the bark of the stem, without killing the shoot. The beginning of the mine is narrow and reddish brown colored, later the gallery, now whitish colored, becomes as wide as the stem. The frass is brown and sometimes interrupted in a central line.
Larvae feed with their venter towards the epidermis.. Pupation external, in an ochraceous cocoon.
Larva lives on Lotus
