Rare
Under 5% of wildlife watchers report a Crimson Marsh Glider sighting in Kaohsiung on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 182nd most-seen of the 218 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, July–August and October–November
In those months about 10% of wildlife watchers report a Crimson Marsh Glider in Kaohsiung on a given day, against under 5% in June, September and December–April, the lowest months. Those are among Kaohsiung's wettest months, with about 210 mm of rain a month against 25 mm in February.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Crimson Marsh Glider sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Crimson Marsh Glider is recorded against all the insects logged in Kaohsiung (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.
