With luck
About 10% of wildlife watchers report a Lighthouse Gall sighting in Minsk on a given day, based on 30 verified sightings from GBIF citizen-science data. It is the 25th most-seen of the 196 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
December

Of the 3 cities where we can rate Lighthouse Gall sightings, Minsk has the highest daily chance: about 10%. Next come Vienna (Austria, under 5%) and London (United Kingdom, under 5%).
GBIF citizen-science records
It is estimated from how often the Lighthouse Gall is recorded against all the insects logged in Minsk (30 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.
