For further information refer UK Moths.

Davey, P., 2009: Found throughout Britain, but local in northern Scotland, the larva feeding on the flowers and ripening seed capsules of wild angelica (Angelica sylvestris), goldenrod (Solidago virgaurea), cow parsley (Anthriscus sylvestris), wild parsnip (Pastinaca sativa), and the flowers of elder (Sambucus nigra). In Dorset, the moth is locally widespread and at low density in the adult stage, but larvae have been reported as common, albeit heavily parasitised, on wild angelica from a number of localities. The larva has also been found on elder.

This species is rather similar to the Grey Pug1837, Golden-rod Pug1851 and Larch Pug1856. Diagnostics include: a white spot on the notum (Larch Pug has white crest on the thorax); white tornal spots on forewing and hindwing; weak darkish costal spots.
