Rare
Under 5% of wildlife watchers report a Holly Tortrix sighting in Helsinki on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 445th 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.
July and August
In those months about 10% of wildlife watchers report a Holly Tortrix in Helsinki on a given day, against under 5% in September to June, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Holly Tortrix sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Yes
Of the 3 cities where we can rate Holly Tortrix sightings, Helsinki has the highest daily chance: under 5%. Next come London (United Kingdom, under 5%) and Moscow (Russia, under 5%).
Same family: Tortricidae
The closest relatives of the Holly Tortrix that you can see in Helsinki (family Tortricidae, Tortricid Leafroller Moths) are Barred Marble (about 10%), Common Marble (about 10%) and White-Foot Bell (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Holly Tortrix is recorded against all the insects logged in Helsinki (16 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.
