Rare
Under 5% of wildlife watchers report a Yellow Satin Veneer sighting in Berlin on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 949th 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 Yellow Satin Veneer in Berlin on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Yellow Satin Veneer sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
8th of 8
Of the 8 cities where we can rate Yellow Satin Veneer sightings, Berlin ranks 8th at under 5%. The best odds are in Helsinki (Finland, about 10%), London (United Kingdom, about 10%) and Rotterdam [The Hague] (Netherlands, about 10%).
GBIF citizen-science records
It is estimated from how often the Yellow Satin Veneer 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.
