With luck
About 10% of wildlife watchers report a Chiasmia emersaria 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.
January and November
In those months about 20% of wildlife watchers report a Chiasmia emersaria in Kolkata on a given day, against under 5% in March–July and September, the lowest months. Those are among Kolkata's driest months, with about 20 mm of rain a month against 330 mm in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Chiasmia emersaria sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
12th of 19
Of the 19 cities where we can rate Chiasmia emersaria sightings, Kolkata ranks 12th at about 10%. The best odds are in Jamshedpur (India, about 30%), Dhaka (Bangladesh, about 20%) and Jabalpur (India, about 20%).
GBIF citizen-science records
It is estimated from how often the Chiasmia emersaria 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.
