Rare
Under 5% of wildlife watchers report a Dusky Groundling sighting in Berlin on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 869th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Dusky Groundling in Berlin on a given day, so our monthly data shows no clear season.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Dusky Groundling 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 Dusky Groundling sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Dusky Groundling is recorded against all the insects logged in Berlin (6 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.
