With luck
About 10% of wildlife watchers report a Siren sighting in Wuhan on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 25th most-seen of the 62 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Siren in Wuhan on a given day, against under 5% in October to April, the lowest months. That is one of Wuhan's wettest months, with about 220 mm of rain against 35 mm in December.
4th of 9
Of the 9 cities where we can rate Siren sightings, Wuhan ranks 4th at about 10%. The best odds are in Hefei (China, about 20%), 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 Wuhan (8 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.
