An extremely rare, very local and declining species in Belgium. Only a few scattered observations after 1980.
The larva is active during day and night and it pupates in a loose cocoon underground. Overwinters as an adult under loose bark or in other sheltered situations. The adults are active from dusk onwards and later they come to light and sugar.
The adults fly in one generation a year; from mid August till mid October and after hibernation again onwards from mid March towards late May.
The larva lives on a variety of woody and herbaceous plants and scrubs like Myrica gale, Calluna vulgaris, Iris pseudacorus, Juncus effusus, Juncus conglomeratus, Polygonum aviculare etc...
