With luck
About 10% of wildlife watchers report a Mango Longhorn Beetle sighting in Hong Kong on a given day, based on 96 verified sightings from GBIF citizen-science data. It is the 119th most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Mango Longhorn Beetle in Hong Kong on a given day, against under 5% in December to March, the lowest months. That is one of Hong Kong's wettest months, with about 190 mm of rain against 25 mm in December.
Among the best
Of the 10 cities where we can rate Mango Longhorn Beetle sightings, Hong Kong ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Tuen Mun (China, about 10%) and Denpasar (Indonesia, about 10%).
Same family: Cerambycidae
The closest relatives of the Mango Longhorn Beetle that you can see in Hong Kong (family Cerambycidae, Longhorn Beetles) are Citrus Longhorn Beetle (about 10%), Kapok Longhorned Borer (about 10%) and Chinaberry Yellow-Banded Longhorn Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mango Longhorn Beetle is recorded against all the insects logged in Hong Kong (96 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.
