Young larvae live on several species of Lamiaceae, making their first case from the leaves. At first they eat flowers and seeds of the food plant. Just before winter they switch to grasses, mining them.
Larvae live from October till May.
There has been a big confusion with Coleophora lixella; therefore all the information in the old literature should be treated with caution.
