Possible
About 20% of wildlife watchers report a Xylena formosa sighting in Nikko National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 53rd most-seen of the 86 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March
In that month about 50% of wildlife watchers report a Xylena formosa in Nikko National Park on a given day, against under 5% in February, April–September and December, the lowest months.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Xylena formosa sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Nikko National Park, in our data
Nikko National Park is the only park on Wallace's Line with enough records to rate Xylena formosa sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Noctuidae
The closest relatives of the Xylena formosa that you can see in Nikko National Park (family Noctuidae, Cutworm Moths and Allies) are Daseochaeta viridis (about 20%), Clavipalpula aurariae (about 20%) and Feralia sauberi (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Xylena formosa is recorded against all the insects logged in Nikko National Park (6 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.
