Rare
Under 5% of wildlife watchers report a Ringed China-Mark sighting in Helsinki on a given day, based on 14 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 Ringed China-Mark in Helsinki on a given day, against under 5% in September to June, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Ringed China-Mark sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 7 cities where we can rate Ringed China-Mark sightings, Helsinki ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Brussels (Belgium, under 5%), London (United Kingdom, under 5%) and Berlin (Germany, under 5%).
Same family: Crambidae
The closest relatives of the Ringed China-Mark that you can see in Helsinki (family Crambidae, Crambid Snout Moths) are Garden Grass-Veneer (about 10%), Barred Grass-Veneer (about 10%) and Common Grass-Veneer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ringed China-Mark is recorded against all the insects logged in Helsinki (14 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.
