ID pointers: An overall light brown or greyish upper-wing covered in coarse yellowish or silvery scales. A light orange-pale yellow head and a pale cross-band at about a third, bordering the darker final third of the wing. Whitish cilia.
Distribution:  (Last record: 16/10/2024 at Monsal Head & Lathkill Dale )  -  With few records of any adults and most relate to the Leaf mines, the species is obviously present in the county in wide scattered localities but relatively uncommon.
Flight Period: May /  August /  -  Two generations in May & August Mine Period: June /  July /  September /  October /   - The first stage of the mine is filled with Frass. The best means of identification is the position of the egg within the mine. The egg is always laid in a vein axil on the underside of a leaf, this helps to identify it from S.microtheriella which most often lays its egg in a vein but not in the axil (A leaf axil is the angle or space fromed where a smaller vein branches off from a larger vein on a leaf). The mines are often found alongside S.microtheriella on the same leaf.
