Possible
About 20% of wildlife watchers report a Yellow-Shouldered Hover Fly sighting in Raipur on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 29th most-seen of the 39 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.

GBIF citizen-science records
It is estimated from how often the Yellow-Shouldered Hover Fly is recorded against all the insects logged in Raipur (7 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.
