With luck
About 10% of wildlife watchers report a Semi-Hyaline Zygaenid Moth sighting in Kolkata on a given day, based on 11 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.
August
In that month about 20% of wildlife watchers report a Semi-Hyaline Zygaenid Moth in Kolkata on a given day, against under 5% in January–March, May and September, the lowest months. That is one of Kolkata's wettest months, with about 310 mm of rain against 10 mm in December.
Among the best
Of the 7 cities where we can rate Semi-Hyaline Zygaenid Moth sightings, Kolkata ranks 5th at about 10%, level with the leaders once rounded. The best odds are in Nanjing (China, about 10%), Tuen Mun (China, about 10%) and Qingdao (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Semi-Hyaline Zygaenid Moth is recorded against all the insects logged in Kolkata (11 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.
