A very local and very rare species in Belgium, thus far only known from the Kempen.
The eggs are oviposited on the underside of the leaves. The larva feeds on the leaves and petioles and it pupates under the leaf or on the herbs in the vicinity. The larvae of the second generation hibernate.
The adults are mainly active in the evening and just after dark.
Two generations a year: in May–June, and again in July–August.
Moorlands, peat bogs.
