Possible
About 30% of wildlife watchers report a Lime Blue sighting in Kanpur on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 13th most-seen of the 31 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
May and December
In those months about 40% of wildlife watchers report a Lime Blue in Kanpur on a given day, against under 5% in March–April and September–October, the lowest months. Those are among Kanpur's driest months, with about 15 mm of rain a month against 260 mm in July.
6th of 27

GBIF citizen-science records
It is estimated from how often the Lime Blue is recorded against all the insects logged in Kanpur (6 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.
