It ranges from Western Europe (Ireland) to Hokkaido (Japan) being found in the northern part of Middle Europe, Northern Europe and Russia to the Amur region.In the western parts of the range it is a local and rare species. It is likely extinct in Britain but a population was recently rediscovered in Ireland. The habitat requirements of the species are a bit unusual, it seems to prefer locally warm deciduous and mixed forests, where birch, the sole host plant, forms the canopy (except Japan(Sorba). The moth survives winter as a pupa underground.
