With luck
About 10% of wildlife watchers report a Great Blackclock sighting in Bavarian Forest National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 471st most-seen of the 1115 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.
February
In that month about 20% of wildlife watchers report a Great Blackclock in Bavarian Forest National Park on a given day, against under 5% in June–September and December–January, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Great Blackclock sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 parks where we can rate Great Blackclock sightings, Bavarian Forest National Park ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Białowieża National Park (Poland, about 10%) and Snowdonia National Park (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Great Blackclock is recorded against all the insects logged in Bavarian Forest National Park (12 verified sightings from 2019 to 2026), 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.
