Rare
Under 5% of wildlife watchers report a Hairy Beech Gall sighting in Berlin on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 562nd 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.
July and October
In those months about 10% of wildlife watchers report a Hairy Beech Gall in Berlin on a given day, against under 5% in August–September and November–June, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Hairy Beech Gall sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 8
Of the 8 cities where we can rate Hairy Beech Gall sightings, Berlin ranks 6th at under 5%. The best odds are in Liverpool (United Kingdom, about 10%), Birmingham (United Kingdom, about 10%) and London (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Hairy Beech Gall is recorded against all the insects logged in Berlin (13 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.
