A new species for Belgium in 2007 in AN. Since then spread out over the whole country, with more observations in the northern part of the country. Status is still rare.
The young larva mines the leaf of Ulmus. The corridor follows the midrib and/or a lateral vein, most of the gallery completely filled with frass.

Pupation in a grey-black, ribbed cocoon.

The adults fly in two generations a year: from April till May and again during July.
