Bordered Sallow Moth

Bordered Sallow MothBordered Sallow Moth

Latin name: Pyrrhia umbra

Forewing length: 16-19mm.

Widespread at low density in southern England. In the Channel Islands it is found only in Alderney, where it is increasing rapidly. More than 20 were recorded in 2013. It usually June/July, but in Alderney it sometimes has a second brood, and can appear much later in the year. It is one of the grassland species that in Alderney has benefited from the work of the grazing herd, as rest-harrow, its larval foodplant, has increased.

Identifying feature: The orange colour of the forewings with their grey outer half distinguish this moth from other closely-related species.
