The autumnal rustic (Eugnorisma glareosa) is a moth of the family Noctuidae. The species was first described by Eugenius Johann Christoph Esper in 1788. It was previously placed in the genus Paradiarsia. It is found in northern and western Europe and North Africa.
The forewings are usually pale grey, distinctively marked with a row of three angular black marks. The ground colour, however, is quite variable with pinkish or reddish forms occurring fairly frequently. In the north of Scotland, including Orkney and Shetland, an almost black form occurs (some authorities regard this as a subspecies, E. g. edda). The hindwings of the typical forms are white, grey in the darker forms. The wingspan is 32–38 mm.
Forewing pearly grey, with fine dark dusting; cell before and beyond orbicular stigma velvety black brown; subbasal and inner lines marked each by a black spot on costa and another below median vein; outer and submarginal lines pale; hindwing whitish, dusted with grey, especially in female - the form edda Stgr. occurring in the Shetland Islands is dark, with forewing red brown and the hindwing dark brown; — rosea Tutt is lilac...

GBIF citizen-science records
It is estimated from how often the Autumnal Rustic is recorded against all the insects logged in Snowdonia National Park (5 verified sightings from 2019 to 2026), calibrated against known sighting rates.
