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.

With luck
About 10% of wildlife watchers report a Pink Lymantria Moth sighting in Dehradun on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 53rd most-seen of the 73 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.
April
In that month about 30% of wildlife watchers report a Pink Lymantria Moth in Dehradun on a given day, against under 5% in June–July and September–March, the lowest months. That is one of Dehradun's driest months, with about 30 mm of rain against 370 mm in July.

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.
2nd of 7
Of the 7 cities where we can rate Pink Lymantria Moth sightings, Dehradun ranks 2nd at about 10%. The best odds are in Sapporo (Japan, about 20%).

GBIF citizen-science records
It is estimated from how often the Pink Lymantria Moth is recorded against all the insects logged in Dehradun (5 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.
