About 20% of wildlife watchers report an Erianthella formosana sighting in Taroko National Park on a given day, based on 23 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 87th most-seen of the 447 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.

Across all the parks we cover, that three-hour window holds the most Erianthella formosana 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 Erianthella formosana sightings: about 20% of wildlife watchers there report one on a given day.
Same order: Orthoptera
The closest relatives of the Erianthella formosana that you can see in Taroko National Park (order Orthoptera, Grasshoppers, Crickets, and Katydids) are Short-Winged Rice Grasshopper (about 50%), Traulia ornata (about 30%) and Cardiodactylus guttulus (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Erianthella formosana is recorded against all the insects logged in Taroko National Park (23 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.
