Rare
Under 5% of wildlife watchers report a Byctiscus betulae sighting in Berlin on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 646th 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.
April and May
In those months about 10% of wildlife watchers report a Byctiscus betulae in Berlin on a given day, against under 5% in June to March, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Byctiscus betulae sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Berlin, in our data
Berlin is the only city on Wallace's Line with enough records to rate Byctiscus betulae sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Byctiscus betulae 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.
