Lymantria mathura
In 3 days ~30% in a week ~60%
Lymantria mathura, the rosy gypsy moth, is a species of moth of the family Erebidae found in the Russian Far East, Nepal, Japan (Hokkaido, Honshu, Kyushu), the Korean Peninsula, northern India and China (at least Hebei, Heilongjiang, Jilin also in the west). The species was first described by Frederic Moore in 1866.
The wingspan is 40–50mm for males and 70–90mm for females. Larvae disperse through ballooning, covering greater distances compared to the Lymantria dispar and exhibiting high rates of settling. Larvae have also been recorded feeding on Terminalia, Shorea, Quercus, Mangifera, Eugenia and Mitragyna. It is considered a pest, since it is a major defoliator of deciduous trees. Their larvae exhibit intraspecific variation to polyphenol metabolism depending on their host plant, allowing them to be polyphagous across multiple broadleaf species.

GBIF citizen-science records
It is estimated from how often the Pink Lymantria Moth is recorded against all the insects logged in Taroko National Park (13 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.
