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 Naha on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 78th most-seen of the 94 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
In that month about 30% of wildlife watchers report a Lymantria xylina in Naha on a given day, against under 5% in July to April, the lowest months. That is one of Naha's wettest months, with about 220 mm of rain against 60 mm in February.
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.
Yes
Of the 2 cities where we can rate Lymantria xylina sightings, Naha has the highest daily chance: about 10%. Next come Taipei (Taiwan, about 10%).
GBIF citizen-science records
It is estimated from how often the Lymantria xylina is recorded against all the insects logged in Naha (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.
