Nationally scarce (Na) on sea cliffs in parts of southern England. Not recorded in Hampshire or on the Isle of Wight to date. Wingspan 12-14 mm. The large and relatively conspicuous, strigulate medio-dorsal blotch of white ground colour is reminiscent of Cydia jungiella which has similar forewing coloration; S. leplastriana may be distinguished by the distinctly triangular pre-tornal marking which reaches the middle of the wing, and in the male by the darker hindwings which in C. jungiella are white [Bradley]. Larva feeds on Wild Cabbage.
