Davey, P., 2009: A species found across England and Wales, but local in Scotland, the larva feeding on the flowers and seed capsules of common toadflax (Linaria vulgaris). In Dorset, the moth is local and at low density, occurring most frequently on Portland, and elsewhere scattered on chalky soil in 'non-native' and transient habitats, such as field edges, dry verges, embankments and disturbed ground. The flight period covers three months on average, and, given the relatively prolonged flowering period of the host foodplant between July and October, it is likely that many of the moths recorded in the late summer are second brood individuals. The species is bivoltine in the southern part of its range on the Continent. Collecting bunches of toadflax seedheads in the autumn have yielded adults the following July.

This species is similar to Foxglove Pug. Diagnostics include: the smaller of the two species; outer edge of the median band less indented close to the costal edge; respective host foodplants, foxglove and common toadflax (Linaria vulgaris), tend to occupy sandy and chalky soils, respectively.
