Thera juniperata
In 3 days ~10% in a week ~30%
The juniper carpet (Thera juniperata) is a moth of the family Geometridae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is found throughout Europe and the Near East, but is rather uncommon and locally distributed, mainly due to its very specific larval food plant. Wikipedia →

Rare
Under 5% of wildlife watchers report a Juniper Carpet sighting in Helsinki on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 413th 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.
October
In that month about 20% of wildlife watchers report a Juniper Carpet in Helsinki on a given day, against under 5% in November to August, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Juniper Carpet 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.
3rd of 6
Of the 6 cities where we can rate Juniper Carpet sightings, Helsinki ranks 3rd at under 5%. The best odds are in Warsaw (Poland, about 10%) and Minsk (Belarus, about 10%).
Same family: Geometridae
The closest relatives of the Juniper Carpet that you can see in Helsinki (family Geometridae, Geometer Moths) are Common Carpet Moth (about 10%), Mottled Umber (about 10%) and Latticed Heath (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Juniper Carpet is recorded against all the insects logged in Helsinki (12 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.
