Found new for Belgium in 1999 in NA. Hitherto a very rare and seldom recorded species.
Native
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; later, the gallery, now whitish colored, becomes as wide as the stem. The frass is brown and sometimes interrupted in a central line.
Ochraceous colored.
Larvae feed with their venter towards the epidermis. Pupation is external, in an ochraceous cocoon.
Limestone grasslands.
