A fairly common species in Belgium, with most observations in the northern part of the country.
The young larva mines mainly in the leaf of Tilia cordata and sometimes also Tilia x vulgaris, in a narrow mine, usually following a leaf-vein.

Later, after the mining, it feeds externally on the underside of the leaf.
Pupation in a cocoon on the trunk of the tree or in leaf litter.
The adults are active in the evening.
The adults fly in two generations a year: in May-June, and in August.
