Local in woodland throughout much of England and Wales. In Hampshire recorded infrequently from a number of widely scattered localities, more often than not at light traps in gardens, where occasionally numerous. Not recorded from the Isle of Wight to date. Wingspan 10-11 mm. One of several, superficially similar black and white gelechiids, S. gemmella is characterised by the pattern of large dorsal and smaller costal spot at base, almost complete outwardly oblique fascia at one-half of costa, spot on costa between this and base, and a spot at tornus (MBGBI Vol 4 part 2). Larva feeds within young shoots of Oak.
