The miller (Acronicta leporina) is a moth of the family Noctuidae. It is found throughout Europe apart from the far south-east. The range extends from the South of Spain, Central Italy and Bulgaria to Scotland and Central Scandinavia, crossing the Arctic Circle in Finland and Norway. Outside Europe it is only known in North Africa. In the Eastern Palearctic and the Nearctic realm it is replaced by Acronicta vulpina, (Grote, 1883) formerly known as Acronicta leporina subspecies vulpina.
This is a variable but always distinctive species, the forewings ranging from almost white to dark grey (pale grey being the most common colour form) with characteristic crescent-shaped black markings. The hindwings are white. The wingspan is 1.5-1.69 in (38–43 mm). Adults of this species fly at night from June to August [1] and will come to light and sugar but are not especially strongly attracted.
Forewing white, the lines indicated by black spots. Larva pale green, or yellowish, with long silky white hairs, which are also sometimes yellowish, curling over the sides; — ab. bradyporina Tr. (3a), occurring in N. Europe and the commoner form... Wikipedia →

Rare
Under 5% of wildlife watchers report a The Miller sighting in Helsinki on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 480th most-seen of the 838 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
August
In that month about 10% of wildlife watchers report a The Miller in Helsinki on a given day, against under 5% in September to July, the lowest months.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most The Miller sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
4th of 8
Of the 8 cities where we can rate The Miller sightings, Helsinki ranks 4th at under 5%. The best odds are in Liverpool (United Kingdom, about 10%), Birmingham (United Kingdom, about 10%) and Manchester (United Kingdom, about 10%).
Same genus: Acronicta
The closest relatives of the The Miller that you can see in Helsinki (genus Acronicta, Dagger Moths) are Sycamore Moth (about 10%), Knot Grass Moth (about 10%) and Alder Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the The Miller is recorded against all the insects logged in Helsinki (10 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.
