Rare
Under 5% of wildlife watchers report a Slender Green-Winged Grasshopper sighting in Hong Kong on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1005th 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.
January
In that month about 10% of wildlife watchers report a Slender Green-Winged Grasshopper in Hong Kong on a given day, against under 5% in February to December, the lowest months. That is one of Hong Kong's driest months, with about 35 mm of rain against 280 mm in June.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Slender Green-Winged Grasshopper sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
25th of 26
Of the 26 cities where we can rate Slender Green-Winged Grasshopper sightings, Hong Kong ranks 25th at under 5%. The best odds are in Naha (Japan, about 30%), Xiuying District (China, about 20%) and Osaka (Japan, about 20%).
Same family: Acrididae
The closest relatives of the Slender Green-Winged Grasshopper that you can see in Hong Kong (family Acrididae, Short-horned Grasshoppers) are Carinate Locust (about 10%), Ceracris nigricornis (about 10%) and Short-Winged Rice Grasshopper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Slender Green-Winged Grasshopper is recorded against all the insects logged in Hong Kong (5 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.
