Rare
Under 5% of wildlife watchers report a Beautiful China-Mark sighting in Helsinki on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 665th 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
In that month about 10% of wildlife watchers report a Beautiful China-Mark in Helsinki on a given day, against under 5% in August to June, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Beautiful China-Mark sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Beautiful China-Mark is recorded against all the insects logged in Helsinki (11 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.
