A very rare and local species in Belgium.
Head ochreous, mixed with some white scales; forewing ground colour pale ochreous, white pattern consisting of a sinuose basal streak, often connected to the first costal stria; four or five costal and four dorsal striae, without any edging; some darker brown scales in the apical area.
The egg is oviposited at the tip of a young, green shoot. The caterpillar mines downwards from this spot. Pupation inside the mine. After emergence of the adult, the pupal skin protrudes from the mine.
One generation a year: May–June.
The species is monophagous on Sarothamnus scoparius.
Dry, sandy, and xerothermic places.
