Rare
Under 5% of wildlife watchers report a Grey Gorse Piercer sighting in London on a given day, based on 5 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 Grey Gorse Piercer in London on a given day, so our monthly data shows no clear season.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Grey Gorse Piercer sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Cydia
The closest relatives of the Grey Gorse Piercer that you can see in London (genus Cydia) are Codling Moth (about 10%) and Marbled Piercer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Grey Gorse Piercer is recorded against all the insects logged in London (5 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.
