Rare
Under 5% of wildlife watchers report a Pear Leaf Blister Moth sighting in London on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 1109th 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.
September
In that month about 10% of wildlife watchers report a Pear Leaf Blister Moth in London on a given day, against under 5% in October to August, the lowest months.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Pear Leaf Blister Moth sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Pear Leaf Blister Moth is recorded against all the insects logged in London (11 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.
