Rare
Under 5% of wildlife watchers report a Japanese Leafhopper sighting in Portland on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 281st most-seen of the 507 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.
August
In that month about 10% of wildlife watchers report a Japanese Leafhopper in Portland on a given day, against under 5% in September to July, the lowest months. That is one of Portland's driest months, with about 20 mm of rain against 250 mm in December.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Japanese Leafhopper sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
18th of 23
Of the 23 cities where we can rate Japanese Leafhopper sightings, Portland ranks 18th at under 5%. The best odds are in Berlin (Germany, about 10%), Munich (Germany, about 10%) and Kyiv (Ukraine, about 10%).
Same family: Cicadellidae
The closest relatives of the Japanese Leafhopper that you can see in Portland (family Cicadellidae, Typical Leafhoppers) are Rhododendron Leafhopper (about 10%), Privet Leafhopper (about 10%) and Blue-Green Sharpshooter (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Japanese Leafhopper is recorded against all the insects logged in Portland (16 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.
