Rare
Under 5% of wildlife watchers report a Spotted Marsh Fly sighting in Berlin on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 801st 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 Spotted Marsh Fly in Berlin on a given day, so our monthly data shows no clear season.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Spotted Marsh Fly sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 4 cities where we can rate Spotted Marsh Fly sightings, Berlin ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Paris (France, under 5%), Vienna (Austria, under 5%) and Helsinki (Finland, under 5%).
GBIF citizen-science records
It is estimated from how often the Spotted Marsh Fly is recorded against all the insects logged in Berlin (7 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.
