With luck
About 10% of wildlife watchers report a Chiasmia emersaria sighting in Chennai on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 84th most-seen of the 376 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.
February
In that month about 30% of wildlife watchers report a Chiasmia emersaria in Chennai on a given day, against under 5% in May and July, the lowest months. That is one of Chennai's driest months, with about 5 mm of rain against 290 mm in November.
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.
8th of 19
Of the 19 cities where we can rate Chiasmia emersaria sightings, Chennai ranks 8th 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 Chennai (39 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.
