With luck
About 10% of wildlife watchers report an Indian Sunbeam sighting in Bengaluru on a given day, based on 36 verified sightings from GBIF citizen-science data. It is the 137th most-seen of the 477 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
March to January
In those months about 10% of wildlife watchers report an Indian Sunbeam in Bengaluru on a given day, against under 5% in February, the lowest month.

GBIF citizen-science records
It is estimated from how often the Indian Sunbeam is recorded against all the insects logged in Bengaluru (36 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.
