With luck
About 10% of wildlife watchers report a Chiasmia emersaria sighting in Bengaluru on a given day, based on 99 verified sightings from GBIF citizen-science data. It is the 62nd most-seen of the 477 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March
In that month about 30% of wildlife watchers report a Chiasmia emersaria in Bengaluru on a given day, against about 10% in April to November, the lowest months. That is one of Bengaluru's driest months, with about 15 mm of rain against 150 mm in September.
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.
6th of 19
Of the 19 cities where we can rate Chiasmia emersaria sightings, Bengaluru ranks 6th 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 Bengaluru (99 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.
