Rare
Under 5% of wildlife watchers report an Iratsume orsedice sighting in Taroko National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 447th most-seen of the 447 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
June and July
In those months about 10% of wildlife watchers report an Iratsume orsedice in Taroko National Park on a given day, against under 5% in August to May, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Iratsume orsedice sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Taroko National Park, in our data

GBIF citizen-science records
It is estimated from how often the Iratsume orsedice is recorded against all the insects logged in Taroko National Park (10 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.
