In 3 days ~10% in a week ~20%
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...

Under 5% of wildlife watchers report an Autumnal Rustic sighting in Pyrénées National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 1026th most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
September and October
In those months about 10% of wildlife watchers report an Autumnal Rustic in Pyrénées National Park on a given day, against under 5% in November to August, the lowest months.

GBIF citizen-science records
It is estimated from how often the Autumnal Rustic is recorded against all the insects logged in Pyrénées National Park (8 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
