Bark mines on Oak (Quercus) are found on a very regular basis but these are indistinguishable from those of Zimmermannia atrifrontella.
Status is insufficiently known but probably underrecorded in our country.
Native
The larva makes a contorted gallery in the smooth bark of branches.

The caterpillar probably has a two year cycle.
Adults fly in June and August, in southern Europa earlier from May till early August.
Mostly on Quercus robur but probably also on other Quercus species.
