In 3 days ~30% in a week ~60%
Lymantria xylina, the casuarina moth or casuarina tussock moth, is a moth in the family Erebidae. The species was first described by Charles Swinhoe in 1903. It is found in Japan, Taiwan and the Chinese provinces of Fujian and Guangdong.
It is a very important forest pest in Taiwan, with outbreaks occurring every five to ten years. The larvae feed on a wide range of host plants, including over 65 species of broadleaf trees. At least one virus is being investigated as a possible biopesticide. Wikipedia →

With luck
About 10% of wildlife watchers report a Lymantria xylina sighting in Taroko National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 135th 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 60%, if each day is a fresh chance.
May and June
In those months about 30% of wildlife watchers report a Lymantria xylina in Taroko National Park on a given day, against under 5% in July to March, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Lymantria xylina sightings with a recorded time, and about 9 in 10 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 Lymantria xylina sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Lymantria
The closest relatives of the Lymantria xylina that you can see in Taroko National Park (genus Lymantria) are Concolorous Tussock Moth (about 20%), Lymantria umbrifera (about 10%) and Pink Lymantria Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Lymantria xylina is recorded against all the insects logged in Taroko National Park (15 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.
