Peribatodes secundaria
In 3 days ~10% in a week ~20%
Peribatodes secundaria, the feathered beauty, is a moth of the family Geometridae. The species was first described by Michael Denis and Ignaz Schiffermüller in 1775. It can be found in Europe. The wingspan is 38–44 mm. The length of the forewings is 17–20 mm. The wing ground colour is grey variously mixed with light brown. The median crossband is dark and partially interrupted. Near the wing outer edge in the middle a light spot is sometimes recognizable. The antennae of the males are strongly feathered in contrast to the filament-shaped of the females.
The moth flies in one generation from mid-June to mid-August.[1] The larva feeds on various coniferous trees, such as the Norway spruce. Wikipedia →

Rare
Under 5% of wildlife watchers report a Feathered Beauty sighting in Copenhagen on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 424th most-seen of the 476 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.
September
In that month about 10% of wildlife watchers report a Feathered Beauty in Copenhagen on a given day, against under 5% in October to August, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Feathered Beauty sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 3 cities where we can rate Feathered Beauty sightings, Copenhagen ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Helsinki (Finland, under 5%) and Berlin (Germany, under 5%).
GBIF citizen-science records
It is estimated from how often the Feathered Beauty is recorded against all the insects logged in Copenhagen (5 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.
