Found in open grassland habitats, including chalk and limestone grasslands, damp woodland rides and wood edges. This moth is similar in apperance to the Scarce Blackneck which has darker forewings often with pale veins and several black spots along the leading edge. The dark kidney mark on the forewings of the Blackneck has one or two spots beside it but on the Scarce Blackneck it is broken along the outer edge.
Easily disturbed by day but rarely flies far before settling. Also flies from dusk.
The larvae can be seen from August to the following May, feeding at night and resting on the foodplant during the day. They pupate in a cocoon on or just beneath the ground.
