Rare
Under 5% of wildlife watchers report an Eristalinus arvorum sighting in Bengaluru on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 433rd most-seen of the 477 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January and June
In those months about 10% of wildlife watchers report an Eristalinus arvorum in Bengaluru on a given day, against under 5% in February–May and July–December, the lowest months. Those are among Bengaluru's driest months, with about 40 mm of rain a month against 150 mm in September.
9th of 9
Of the 9 cities where we can rate Eristalinus arvorum sightings, Bengaluru ranks 9th at under 5%. The best odds are in Prayagraj (India, about 10%), Changsha (China, about 10%) and Kolkata (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Eristalinus arvorum is recorded against all the insects logged in Bengaluru (5 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.
