A rare species in Belgium.

The larva makes a mine in the leaves of Humulus lupulus. It starts as an irregular gallery by a vein or along the midrib and in this the larva constructs a silk-lined gallery which serves as a shelter when not feeding. From this it mines several feeding branches in all directions. When fully-fed, the larva leaves the mine and hibernates in a white elongate cocoon and pupates in the same cocoon in plant debris on the ground. 

The adults fly in one generation a year; from late May towards July. They fly around the foodplant at dusk and later comes occasionally to light.
