Davey, P., 2009: A species found over much of Britain, but local in Scotland, the larva feeding on norway spruce (Picea abies), sitka spruce (Picea sitchensis), douglas fir (Pseudotsuga menziesii) and western hemlock-spruce (Tsuga heterophylla). In Dorset, the moth is common in spruce and fir plantation. The moth is bivoltine with two brood cycles paralleling those of the Grey Pine Carpet1768. The length of time between the peaks of a given cycle is roughly one hundred and twenty-nine days. The following singletons observed at light traps between January and March may be partial third brood individuals: Puddletown, on 24 December 2000, 7 January 2003 (H Wood Homer), Bere Wood, two on 15 March 1997 (R Cook et al).
