With luck
About 10% of wildlife watchers report a Brown-Marmorated Longicorn Beetle sighting in Taroko National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 181st most-seen of the 447 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.
May–June and December
In those months about 20% of wildlife watchers report a Brown-Marmorated Longicorn Beetle in Taroko National Park on a given day, against under 5% in February–March and July–October, the lowest months.
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.
Only Taroko National Park, in our data
Taroko National Park is the only park on Wallace's Line with enough records to rate Brown-Marmorated Longicorn Beetle sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Brown-Marmorated Longicorn Beetle is recorded against all the insects logged in Taroko National Park (11 verified sightings from 2019 to 2026), 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.
