Rare
Under 5% of wildlife watchers report a Drinker Moth sighting in Copenhagen on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 260th 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 30%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report a Drinker Moth in Copenhagen on a given day, against under 5% in July to April, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Drinker Moth sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 9
Of the 9 cities where we can rate Drinker Moth sightings, Copenhagen ranks 3rd at under 5%. The best odds are in Manchester (United Kingdom, about 10%) and Liverpool (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Drinker Moth is recorded against all the insects logged in Copenhagen (10 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.
