With luck
About 10% of wildlife watchers report a Slate Flash sighting in Bengaluru on a given day, based on 60 verified sightings from GBIF citizen-science data. It is the 94th most-seen of the 477 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
September and October
In those months about 20% of wildlife watchers report a Slate Flash in Bengaluru on a given day, against about 10% in November to August, the lowest months. Those are among Bengaluru's wettest months, with about 150 mm of rain a month against almost none in January.
Among the best
Of the 12 cities where we can rate Slate Flash sightings, Bengaluru ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Pune (India, about 10%), Salem (India, about 10%) and Tuen Mun (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Slate Flash is recorded against all the insects logged in Bengaluru (60 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.
