The caterpillar is capable of changing to another leaf whenever the food in the first leaf is exhausted. Frass is ejected from the mine. Pupation between fallen leaves on the ground. The adults come to light.
The adults fly in one generation a year: from early May towards mid July with a peak around mid May.
The larva feeds mainly on Cytisus scoparius but has also been recorded from: Genista, Laburnum and Lupinus.
