With luck
About 10% of wildlife watchers report a Thyrassia subcordata sighting in Kolkata on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 124th 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 50%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Thyrassia subcordata in Kolkata on a given day, against under 5% in July and November–April, the lowest months. That is one of Kolkata's wettest months, with about 230 mm of rain against 10 mm in December.
Among the best
Of the 4 cities where we can rate Thyrassia subcordata sightings, Kolkata ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Prayagraj (India, about 10%) and Kochi (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Thyrassia subcordata 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.
