Rare
Under 5% of wildlife watchers report a Brown-Marmorated Longicorn Beetle sighting in Taipei on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 344th most-seen of the 765 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May and June
In those months about 10% of wildlife watchers report a Brown-Marmorated Longicorn Beetle in Taipei on a given day, against under 5% in July to April, the lowest months. Those are among Taipei's wettest months, with about 250 mm of rain a month against 90 mm in February.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Brown-Marmorated Longicorn Beetle sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 cities where we can rate Brown-Marmorated Longicorn Beetle sightings, Taipei ranks 2nd at under 5%. The best odds are in Taichung (Taiwan, about 10%).
Same family: Cerambycidae
The closest relatives of the Brown-Marmorated Longicorn Beetle that you can see in Taipei (family Cerambycidae, Longhorn Beetles) are Yellow-Spotted Longicorn Beetle (about 10%), Apriona rugicollis (about 10%) and White-Spotted Longicorn Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Brown-Marmorated Longicorn Beetle is recorded against all the insects logged in Taipei (22 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.
