A rather rare species throughout Belgium, though widespread and recorded from all provinces.
Head brown mixed with many white hairs; forewing ground colour brown; white pattern consisting of a straight basal line edged with dark brawn scales, a patch near the base at the dorsum, four costal and three dorsal striae; a small patch of dark brown scales in the apical area.
No real cocoon is formed inside the mine, only some spinning.
Pupation inside the mine. The species hibernates in the pupal stage. The pupal skin protrudes from the mine after emergence of the adult.
The adults rest on tree trunks or in the foliage during day time. They become active at dusk and come to light.
The adults fly in two generations a year: May and August.
Forest edges and clearings, parks and gardens with Viburnum planted as ornamental plants.
