With luck
About 10% of wildlife watchers report a Spiral Borer sighting in Kolkata on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 129th most-seen of the 213 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.
September and December
In those months about 20% of wildlife watchers report a Spiral Borer in Kolkata on a given day, against under 5% in February–May, August and October, the lowest months.

Same order: Coleoptera

GBIF citizen-science records
It is estimated from how often the Spiral Borer is recorded against all the insects logged in Kolkata (12 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.
