Rare
Under 5% of wildlife watchers report a Chimney-Sweeper sighting in Helsinki on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 360th 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.
June and July
In those months about 10% of wildlife watchers report a Chimney-Sweeper in Helsinki on a given day, against under 5% in August to May, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Chimney-Sweeper sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 3
Of the 3 cities where we can rate Chimney-Sweeper sightings, Helsinki ranks 2nd at under 5%. The best odds are in Birmingham (United Kingdom, about 10%).
Same family: Geometridae
The closest relatives of the Chimney-Sweeper 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 Chimney-Sweeper is recorded against all the insects logged in Helsinki (15 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.
