With luck
About 10% of wildlife watchers report a Common Rose Swallowtail sighting in New Delhi on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 68th most-seen of the 174 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.

GBIF citizen-science records
It is estimated from how often the Common Rose Swallowtail is recorded against all the insects logged in New Delhi (27 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.
