Rare
Under 5% of wildlife watchers report a Feathered Gothic sighting in Berlin on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 694th 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.
August and September
In those months about 10% of wildlife watchers report a Feathered Gothic in Berlin on a given day, against under 5% in October to July, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Feathered Gothic 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.
Among the best
Of the 6 cities where we can rate Feathered Gothic sightings, Berlin ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Helsinki (Finland, under 5%) and Prague (Czechia, under 5%).
Same family: Noctuidae
The closest relatives of the Feathered Gothic that you can see in Berlin (family Noctuidae, Cutworm Moths and Allies) are Large Yellow Underwing (about 20%), Silver Υ (about 10%) and Heart And Dart (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Feathered Gothic is recorded against all the insects logged in Berlin (16 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.
