Possible
About 20% of wildlife watchers report a Siren sighting in Hefei on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 21st most-seen of the 44 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
April
In that month about 40% of wildlife watchers report a Siren in Hefei on a given day, against under 5% in March, July–August and October–January, the lowest months.
Yes
Of the 9 cities where we can rate Siren sightings, Hefei has the highest daily chance: about 20%. Next come Nanjing (China, about 20%) and Nagoya (Japan, about 10%).
GBIF citizen-science records
It is estimated from how often the Siren is recorded against all the insects logged in Hefei (6 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.
