With luck
About 10% of wildlife watchers report a Vindhyan Bob sighting in Mumbai on a given day, based on 53 verified sightings from GBIF citizen-science data. It is the 84th most-seen of the 362 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.

GBIF citizen-science records
It is estimated from how often the Vindhyan Bob is recorded against all the insects logged in Mumbai (53 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.
