Similar species: 1955 Cabera pusaria (Common White Wave).

For further information refer UK Moths.

Davey, P., 2009: A frequent species in Britain, the larva feeding on sallow (Salix spp.) and aspen (Populus tremens). In Dorset, the moth frequents sallow-rich habitat which is mainly, but not exclusively, in damp situations; it is seldom seen far from sallow-rich habitat. The moth is double brooded in Dorset, but, like the Common White Wave1955, relatively high numbers between the respective brood peaks in late-May and mid-August suggest an additional univoltine cycle.

Care is needed to correctly identify this and Common White Wave1955. Diagnostics include: weakly-marked cross lines; smoothly-curved cross lines (not straight).
