A not so common species, but known from many localities throughout Belgium, especially in the Kempen and the southern part of the country.
The larva lives in a case which it constructs from grasses of different species of Gramineae.
The female lacks legs, antennae and is apterous and remains in the case during its entire life, attracting the male by scent. The males fly arround noon in sunshine.
One generation a year: from late April till the end of June.
Meadows, forest clearings, moorland.
