Stainton, 1851Wingspan 8-9 mm.
A relatively common species around the coastal saltings of England and Wales, though probably overlooked as an adult due to its size. It bears a superficial resemblance to some of the Phyllonorycter species.
The larva feeds on sea aster (Aster tripolium), creating a narrow gallery containing black or brownish frass, and subsequently one or more shorter mines or windows.
The adult moths fly in June and August, in two generations. They are on the wing in late afternoon sunshine but also occasionally come to light.
