Rare
Under 5% of wildlife watchers report a Xyleutes strix sighting in Taipei on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 703rd most-seen of the 765 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.
August
In that month about 10% of wildlife watchers report a Xyleutes strix in Taipei on a given day, against under 5% in September to July, the lowest months. That is one of Taipei's wettest months, with about 260 mm of rain against 90 mm in February.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Xyleutes strix sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Taipei, in our data
Taipei is the only city on Wallace's Line with enough records to rate Xyleutes strix sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Lepidoptera
The closest relatives of the Xyleutes strix that you can see in Taipei (order Lepidoptera, Butterflies and Moths) are Rose Myrtle Lappet Moth (about 30%), Common Mapwing (about 20%) and Great Mormon Swallowtail (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Xyleutes strix is recorded against all the insects logged in Taipei (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.
