Rare
Under 5% of wildlife watchers report a Horned Treehopper sighting in Nizhny Novgorod on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 293rd most-seen of the 405 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.
June
In that month about 10% of wildlife watchers report a Horned Treehopper in Nizhny Novgorod on a given day, against under 5% in July to May, the lowest months. That is one of Nizhny Novgorod's wettest months, with about 85 mm of rain against 40 mm in February.
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.
5th of 10
Of the 10 cities where we can rate Horned Treehopper sightings, Nizhny Novgorod ranks 5th at under 5%. The best odds are in Kyiv (Ukraine, about 10%), Lyon (France, under 5%) and Novosibirsk (Russia, under 5%).
GBIF citizen-science records
It is estimated from how often the Horned Treehopper is recorded against all the insects logged in Nizhny Novgorod (6 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.
