Rare
Under 5% of wildlife watchers report a White-Barred Tortrix sighting in London on a given day, based on 50 verified sightings from GBIF citizen-science data. It is the 528th 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 30%, if each day is a fresh chance.
June and September
In those months about 10% of wildlife watchers report a White-Barred Tortrix in London on a given day, against under 5% in July–August and October–May, the lowest months.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate White-Barred Tortrix sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Tortricidae
The closest relatives of the White-Barred 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 White-Barred Tortrix is recorded against all the insects logged in London (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.
