In 3 days ~10% in a week ~20%
The nutmeg (Hadula trifolii or Anarta trifolii), also known as the clover cutworm, is a moth of the family Noctuidae. It is found in the Western Palearctic (western Europe, Tunisia, Iran), Niger, and Quebec in North America. In the north of its European range it is a summer migrant, not being able to survive the cold winters.
This is a small to medium (wingspan 33–39 mm) species with cryptically coloured forewings, varying from light to dark brown, sometimes with a reddish tinge. The most characteristic feature is a distinctively W-shaped, white subterminal line. This feature is seen on some other noctuids, but usually much larger species. The hindwings are grey or buff, darker towards the termen, and marked with dark veins.
Forewing grey, dark speckled:costa black-spotted: claviform stigma small: orbicular round, pale, sometimes whitish: reniform large, the lower lobe dark grey, all three finely black-edged; veins towards termen finely black; hindwing
dull whitish, with abroad border and the veins fuscous. — saucia Esp. is the form showing a tendency to an ochreous tint; - in ab. farkasii Tr. the forewing is more variegated... Wikipedia →

Rare
Under 5% of wildlife watchers report a Nutmeg Moth sighting in Helsinki on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 602nd 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 20%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report a Nutmeg Moth in Helsinki on a given day, against under 5% in September to June, the lowest months.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most Nutmeg Moth 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.
8th of 13
Of the 13 cities where we can rate Nutmeg Moth sightings, Helsinki ranks 8th at under 5%. The best odds are in Budapest (Hungary, about 20%), Kyiv (Ukraine, about 10%) and Kharkiv (Ukraine, about 10%).
Same family: Noctuidae
The closest relatives of the Nutmeg Moth that you can see in Helsinki (family Noctuidae, Cutworm Moths and Allies) are Large Yellow Underwing (about 10%), Silver Υ (about 10%) and Antler Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Nutmeg Moth is recorded against all the insects logged in Helsinki (7 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.
