Norfolk status Similar to Apotomis betuletana but shows a stronger hook like indentation to the outer edge of the median fascia, this can be hard to interpret as betuletana shows a weak indentation so care should be exercised. The median fascia is more concave (not straight as in betuletana) appearing to curve along the costal edge of the forewing, stronger black dots set in the subterminal fascia.
Locally recorded in open woodland, margins of woods, gravel pits, marshes and banks of streams. Occurring mainly in the southern counties of England and Wales.
