With luck
About 10% of wildlife watchers report a Common Bluebottle sighting in Guangzhou on a given day, based on 80 verified sightings from GBIF citizen-science data. It is the 25th most-seen of the 482 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
March, May and October
In those months about 20% of wildlife watchers report a Common Bluebottle in Guangzhou on a given day, against under 5% in January, the lowest month.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Common Bluebottle sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
34th of 36

GBIF citizen-science records
It is estimated from how often the Common Bluebottle is recorded against all the insects logged in Guangzhou (80 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.
