Nationally Scarce A
Suspected occasional immigrant and probable resident. Scarce, and distinctly episodic in appearance. Single-brooded, flying in May, but mainly from the third week of July to mid August. Larvae feed in the cones of Norway spruce although this has yet to be confirmed in Sussex. (Pratt, 2011).
