In Belgium mainly observed in the Kempen and in the south of the country, but the species has been recorded throughout our country.
The larva needs two years for its development.
The female is apterous and usually stays in the case during its entire life.
Adults emerge at night and males come to light.
One generation a year: from late May till late July.
Forests, but also open areas, heathland, moorland.
