A rather rare species throughout Belgium, though widespread and recorded from all provinces.
Native
Head brown mixed with many white hairs; forewing ground color brown; white pattern consisting of a straight basal line edged with dark brown 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.
A long, whitish tentiform mine on the underside of a leaf, between two secondary veins. The mine can extend from the midrib to the leaf margin, contorting the leaf very strongly. In the last stage, the mine colors are brown.

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 the emergence of the adult.
The adults rest on tree trunks or in the foliage during the daytime. They become active at dusk and come to light.
The adults fly in two generations a year in May and August.
The larva lives mainly on Viburnum lantana, but can occasionally be found on: Viburnum opulus, V. tinus and very exceptionally on Sorbus aucuparia.
Forest edges and clearings, parks and gardens with Viburnum planted as ornamental plants.
