For further information refer UK Moths.

Davey, P., 2009: A frequent species in Britain, the larva feeding on birch (Betula spp.), alder (Alnus spp.), sallow (Salix spp.), and a variety of other deciduous tree and shrub species. In Dorset, the moth is widespread and common to abundant in old deciduous woodland, particularly those with sizeable stocks of host foodplant.

Diagnostic: yellow thorax, so yellow that wasps often target and kill the moth as if it were a threat to them.
