A rare species in most areas of Belgium, though widespread all over the country.
The young larva mines a fresh twig of the foodplant and later it lives between spun twigs.
It hibernates as a young larva in the twig.
Adults hide during the day and they are rarely seen on light.
One or two indistinct generations a year: from March till September.
Monophagous on Sarothamnus scoparius, though it has been occasionally recorded from Genista as well.
Open, sandy areas.
