With luck
About 10% of wildlife watchers report a New Holm-Oak Pigmy sighting in London on a given day, based on 142 verified sightings from GBIF citizen-science data. It is the 239th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
February and March
In those months about 20% of wildlife watchers report a New Holm-Oak Pigmy in London on a given day, against under 5% in June to August, the lowest months.
Only London, in our data

GBIF citizen-science records
It is estimated from how often the New Holm-Oak Pigmy is recorded against all the insects logged in London (142 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.
