Rare
Under 5% of wildlife watchers report a Barred Sycamore Pigmy sighting in Berlin on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 745th most-seen of the 1065 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.
October and November
In those months about 10% of wildlife watchers report a Barred Sycamore Pigmy in Berlin on a given day, against under 5% in December to September, the lowest months.
Only Berlin, in our data
Berlin is the only city on Wallace's Line with enough records to rate Barred Sycamore Pigmy sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Barred Sycamore Pigmy is recorded against all the insects logged in Berlin (9 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.
