Rare
Under 5% of wildlife watchers report a Buttoned Snout sighting in Copenhagen on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 234th 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.
February, August and December
In those months about 10% of wildlife watchers report a Buttoned Snout in Copenhagen on a given day, against under 5% in January, March–July and September–November, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Buttoned Snout sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
8th of 13
Of the 13 cities where we can rate Buttoned Snout sightings, Copenhagen ranks 8th at under 5%. The best odds are in Kyiv (Ukraine, about 10%), Berlin (Germany, about 10%) and Almaty (Kazakhstan, about 10%).
GBIF citizen-science records
It is estimated from how often the Buttoned Snout is recorded against all the insects logged in Copenhagen (12 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.
