With luck
About 10% of wildlife watchers report a Trioza urticae sighting in Berlin on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 277th most-seen of the 1065 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
April–June and December–February
In those months about 10% of wildlife watchers report a Trioza urticae in Berlin on a given day, against under 5% in March and July–November, the lowest months.
Yes
Of the 4 cities where we can rate Trioza urticae sightings, Berlin has the highest daily chance: about 10%. Next come Paris (France, under 5%) and London (United Kingdom, under 5%).
GBIF citizen-science records
It is estimated from how often the Trioza urticae is recorded against all the insects logged in Berlin (32 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.
