Fairly common in the Kempen area, especially in heathland habitats, elsewhere in Belgium a rather rare appearance.
Native
Head and prothoracic plate pale brown with blackish markings; abdomen blackish with yellow dorsal, sub-dorsal and spiracular lines, sometimes rosy tinged; anal plate whitish; pinacula white with black centre (Gregersen & Karsholt 2022).
The larva lives in a silken tube amongst the shoots and among twigs on the food plant. The larvae easily drop upon disturbance. Pupation in a loose cocoon on the foodplant.
The butterflies are easy to hunt during the day when they rest among the heathland vegetation. They are often active during the day in warm weather and later come to light.
The adults have been seen from early June towards mid-September with most observations during July.
The larva lives on Calluna vulgaris, Erica cinerea, Erica tetralix and Empetrum nigrum.
