Rare
Under 5% of wildlife watchers report a Brown Leaf Weevil sighting in Warsaw on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 501st most-seen of the 580 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.

In that month about 10% of wildlife watchers report a Brown Leaf Weevil in Warsaw on a given day, against under 5% in June to April, the lowest months. That is one of Warsaw's wettest months, with about 75 mm of rain against 40 mm in February.
17th of 19
Of the 19 cities where we can rate Brown Leaf Weevil sightings, Warsaw ranks 17th at under 5%. The best odds are in Sofia (Bulgaria, about 10%), Budapest (Hungary, about 10%) and Turin (Italy, about 10%).
GBIF citizen-science records
It is estimated from how often the Brown Leaf Weevil is recorded against all the insects logged in Warsaw (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.
