Possible
About 30% of wildlife watchers report a Black Giant Cicada sighting in Hiroshima on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 6th most-seen of the 14 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
August
In that month about 60% of wildlife watchers report a Black Giant Cicada in Hiroshima on a given day, against under 5% in February–June and September–December, the lowest months.
4th of 6
Of the 6 cities where we can rate Black Giant Cicada sightings, Hiroshima ranks 4th at about 30%. 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 Hiroshima (7 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.
