Lymantria mathura
In 3 days ~10% in a week ~20%
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.

Rare
Under 5% of wildlife watchers report a Pink Lymantria Moth sighting in Hong Kong on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 583rd most-seen of the 1125 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.
May–June and October
In those months about 10% of wildlife watchers report a Pink Lymantria Moth in Hong Kong on a given day, against under 5% in July–September and November–April, the lowest months. Those are among Hong Kong's wettest months, with about 180 mm of rain a month against 25 mm in December.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Pink Lymantria Moth sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
6th of 7
Of the 7 cities where we can rate Pink Lymantria Moth sightings, Hong Kong ranks 6th at under 5%. The best odds are in Sapporo (Japan, about 20%), Dehradun (India, about 10%) and Taipei (Taiwan, about 10%).
GBIF citizen-science records
It is estimated from how often the Pink Lymantria Moth is recorded against all the insects logged in Hong Kong (16 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.
