With luck
About 10% of wildlife watchers report a Tissue sighting in Helsinki on a given day, based on 50 verified sightings from GBIF citizen-science data. It is the 100th most-seen of the 838 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
August–September and November
In those months about 20% of wildlife watchers report a Tissue in Helsinki on a given day, against under 5% in February–July and December, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Tissue sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Yes
Of the 3 cities where we can rate Tissue sightings, Helsinki has the highest daily chance: about 10%. Next come Munich (Germany, under 5%) and Vienna (Austria, under 5%).
Same family: Geometridae
The closest relatives of the Tissue 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 Tissue is recorded against all the insects logged in Helsinki (50 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.
