Possible
About 20% of wildlife watchers report a Greater Blue Skimmer sighting in Nagoya on a given day, based on 26 verified sightings from GBIF citizen-science data. It is the 31st most-seen of the 195 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.
July
In that month about 40% of wildlife watchers report a Greater Blue Skimmer in Nagoya on a given day, against under 5% in February–May and September–December, the lowest months. That is one of Nagoya's wettest months, with about 230 mm of rain against 75 mm in January.
2nd of 11
Of the 11 cities where we can rate Greater Blue Skimmer sightings, Nagoya ranks 2nd at about 20%. The best odds are in Naha (Japan, about 30%).
GBIF citizen-science records
It is estimated from how often the Greater Blue Skimmer is recorded against all the insects logged in Nagoya (26 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.
