Rare
Under 5% of wildlife watchers report a Holly Tortrix sighting in London on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1394th most-seen of the 1504 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Holly Tortrix in London on a given day, so our monthly data shows no clear season.
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.
Among the best
Of the 3 cities where we can rate Holly Tortrix sightings, London ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Helsinki (Finland, under 5%).
Same family: Tortricidae
The closest relatives of the Holly Tortrix that you can see in London (family Tortricidae, Tortricid Leafroller Moths) are Light Brown Apple Moth (about 20%), Common Marble (about 10%) and Clepsis dumicolana (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 London (6 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.
