Wingspan c. 11mm
This moth occurs in south and south-east England, where its presence may be suggested by locating exit-holes of the adult moths in fallen cones of the foodplant in mature pine woods.
The adult moths fly in May and June and are active during morning, afternoon and dusk.
The larva bores into a young cone of pine (Pinus ), especially Scots pine (P. sylvestris) and feeds internally on the seeds, overwintering. The only external evidence that a cone is occupied is the small exit hole once the moth has emerged.
