Possible
About 20% of wildlife watchers report a Black Giant Cicada sighting in Fukuoka on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 8th most-seen of the 26 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.
July and August
In those months about 40% of wildlife watchers report a Black Giant Cicada in Fukuoka on a given day, against under 5% in September to June, the lowest months. Those are among Fukuoka's wettest months, with about 280 mm of rain a month against 70 mm in January.
5th of 6
Of the 6 cities where we can rate Black Giant Cicada sightings, Fukuoka ranks 5th at about 20%. The best odds are in Nagoya (Japan, about 50%), Osaka (Japan, about 30%) and Naha (Japan, about 30%).
GBIF citizen-science records
It is estimated from how often the Black Giant Cicada is recorded against all the insects logged in Fukuoka (10 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.
