Rare
Under 5% of wildlife watchers report a Horned Leafhopper sighting in Porto on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 305th most-seen of the 498 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.
June–August and December
In those months about 10% of wildlife watchers report a Horned Leafhopper in Porto on a given day, against under 5% in January–May and September–November, the lowest months. Those are among Porto's driest months, with about 45 mm of rain a month against 140 mm in January.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Horned Leafhopper 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.
3rd of 9
Of the 9 cities where we can rate Horned Leafhopper sightings, Porto ranks 3rd at under 5%. The best odds are in London (United Kingdom, about 10%) and Istanbul (Turkey, about 10%).
GBIF citizen-science records
It is estimated from how often the Horned Leafhopper is recorded against all the insects logged in Porto (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.
