Rare
Under 5% of wildlife watchers report a Horned Treehopper sighting in Copenhagen on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 304th 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.
May and June
In those months about 10% of wildlife watchers report a Horned Treehopper in Copenhagen on a given day, against under 5% in July to April, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Horned Treehopper sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 10
Of the 10 cities where we can rate Horned Treehopper sightings, Copenhagen ranks 6th at under 5%. The best odds are in Kyiv (Ukraine, about 10%), Lyon (France, under 5%) and Novosibirsk (Russia, under 5%).
Same order: Hemiptera
The closest relatives of the Horned Treehopper that you can see in Copenhagen (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are European Firebug (about 20%), Green Shield Bug (about 20%) and Western Conifer Seed Bug (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Horned Treehopper is recorded against all the insects logged in Copenhagen (9 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.
