With luck
About 10% of wildlife watchers report a Woodland Grayling sighting in Budapest on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 209th most-seen of the 404 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June to September
In those months about 10% of wildlife watchers report a Woodland Grayling in Budapest on a given day, against under 5% in October to May, the lowest months.

GBIF citizen-science records
It is estimated from how often the Woodland Grayling is recorded against all the insects logged in Budapest (10 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.
