A not so common species throughout Belgium.
The larva lives in the rootstock, tunnelling down into the roots of the food plant. Pupation in a silken cocoon in the larval habitation.
The adults are readily disturbed from rest during the day. They are active towards late afternoon and later come sparsely to light.
The adults fly in two generations a year from end of April till early June and again during August and September.
The larva lives in the rootstock of Leucanthemum vulgare and Tanacetum vulgare.
