With luck
About 10% of wildlife watchers report a Three-Striped Lady Beetle sighting in Prayagraj on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 85th most-seen of the 117 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
April and July
In those months about 30% of wildlife watchers report a Three-Striped Lady Beetle in Prayagraj on a given day, against under 5% in May–June and August–February, the lowest months. Those are among Prayagraj's wettest months, with about 140 mm of rain a month against almost none in November.

GBIF citizen-science records
It is estimated from how often the Three-Striped Lady Beetle is recorded against all the insects logged in Prayagraj (10 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.
