Rare
Under 5% of wildlife watchers report a Sphenoraia nebulosa sighting in Hong Kong on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 680th 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.
May and August–September
In those months about 10% of wildlife watchers report a Sphenoraia nebulosa in Hong Kong on a given day, against under 5% in June–July and October–April, the lowest months. Those are among Hong Kong's wettest months, with about 200 mm of rain a month against 25 mm in December.
2nd of 2
Of the 2 cities where we can rate Sphenoraia nebulosa sightings, Hong Kong ranks 2nd at under 5%. The best odds are in Tuen Mun (China, about 10%).
Same family: Chrysomelidae
The closest relatives of the Sphenoraia nebulosa that you can see in Hong Kong (family Chrysomelidae, Leaf Beetles) are Podontia lutea (about 10%), Furcated Tortoise Beetle (about 10%) and Abirus fortuneii (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sphenoraia nebulosa is recorded against all the insects logged in Hong Kong (11 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.
