Rare
Under 5% of wildlife watchers report a White-Backed Planthopper sighting in Hong Kong on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 819th most-seen of the 1125 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 White-Backed Planthopper in Hong Kong on a given day, against under 5% in September to July, the lowest months. That is one of Hong Kong's wettest months, with about 220 mm of rain against 25 mm in December.
Among the best
Of the 2 cities where we can rate White-Backed Planthopper sightings, Hong Kong ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Mumbai (India, under 5%).
Same order: Hemiptera
The closest relatives of the White-Backed Planthopper that you can see in Hong Kong (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are Litchi Lantern Bug (about 20%), Lychee Stink Bug (about 20%) and Ricania guttata (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-Backed Planthopper is recorded against all the insects logged in Hong Kong (8 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.
