With luck
About 10% of wildlife watchers report a Yellow-Spotted Longicorn Beetle sighting in Taichung on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 155th most-seen of the 197 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Yellow-Spotted Longicorn Beetle in Taichung on a given day, against under 5% in July, September and December–April, the lowest months. That is one of Taichung's wettest months, with about 330 mm of rain against 40 mm in December.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellow-Spotted Longicorn Beetle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
10th of 11
Of the 11 cities where we can rate Yellow-Spotted Longicorn Beetle sightings, Taichung ranks 10th at about 10%. The best odds are in Nanjing (China, about 20%), Nagoya (Japan, about 10%) and Naha (Japan, about 10%).
Same family: Cerambycidae
The closest relatives of the Yellow-Spotted Longicorn Beetle that you can see in Taichung (family Cerambycidae, Longhorn Beetles) are Dicelosternus corallinus (about 10%), White-Spotted Longicorn Beetle (about 10%) and Apriona rugicollis (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow-Spotted Longicorn Beetle is recorded against all the insects logged in Taichung (6 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.
