As imago very rarely observed in Belgium, but quite commonly found as a larva. Nowadays only in WV, recently (2019) found again in LG and 2021 in LX.
The larva lives between spun leaves and also on buds on the food plant and it feeds in September and again after hibernation from May to June.
From mid-June to early August.
Along the North Sea coast it is found in sandy places and dunes with stands of Salix repens. In the higher regions and Ardennes it is found in peat bogs, marshy areas and high moors with Vaccinium.
