With luck
About 10% of wildlife watchers report a Great Mormon Swallowtail sighting in Fukuoka on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 19th most-seen of the 26 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.
August
In that month about 40% of wildlife watchers report a Great Mormon Swallowtail in Fukuoka on a given day, against under 5% in October to June, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Great Mormon Swallowtail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
22nd of 39
Of the 39 cities where we can rate Great Mormon Swallowtail sightings, Fukuoka ranks 22nd at about 10%. The best odds are in Hanoi (Vietnam, about 40%), Yogyakarta (Indonesia, about 30%) and Jakarta (Indonesia, about 30%).
GBIF citizen-science records
It is estimated from how often the Great Mormon Swallowtail is recorded against all the insects logged in Fukuoka (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.
