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...

Rare
Under 5% of wildlife watchers report an Autumnal Rustic sighting in London on a given day, based on 28 verified sightings from GBIF citizen-science data. It is the 673rd most-seen of the 1504 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
In that month about 10% of wildlife watchers report an Autumnal Rustic in London on a given day, against under 5% in October to August, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Autumnal Rustic sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Autumnal Rustic sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Noctuidae
The closest relatives of the Autumnal Rustic that you can see in London (family Noctuidae, Cutworm Moths and Allies) are Large Yellow Underwing (about 30%), Heart And Dart (about 20%) and Shuttle-Shaped Dart (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Autumnal Rustic is recorded against all the insects logged in London (28 verified sightings), 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.
