The species occurs in western Eurasia east of France; it is also found in Great Britain but appears to be absent from the Balkans. Its caterpillars feed mainly on fungi, namely birch polypore (Fomitopsis betulina) and turkey tail (Trametes versicolor). To a lesser extent, they eat rotting wood.Grabe (1942), FE (2009), and see references in Savela (2001)
