Rare
Under 5% of wildlife watchers report a Stromatium longicorne sighting in Guangzhou on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 355th most-seen of the 482 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
In that month about 10% of wildlife watchers report a Stromatium longicorne in Guangzhou on a given day, against under 5% in June to April, the lowest months. That is one of Guangzhou's wettest months, with about 280 mm of rain against 30 mm in December.
3rd of 3
Of the 3 cities where we can rate Stromatium longicorne sightings, Guangzhou ranks 3rd at under 5%. The best odds are in Tuen Mun (China, about 10%) and Hong Kong (China, under 5%).
Same family: Cerambycidae
The closest relatives of the Stromatium longicorne that you can see in Guangzhou (family Cerambycidae, Longhorn Beetles) are Mango Longhorn Beetle (about 10%), Kapok Longhorned Borer (about 10%) and Citrus Longhorn Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Stromatium longicorne is recorded against all the insects logged in Guangzhou (7 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.
