Possible
About 20% of wildlife watchers report a Chiasmia emersaria sighting in Dhaka on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 40th most-seen of the 92 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
October to December
In those months about 40% of wildlife watchers report a Chiasmia emersaria in Dhaka on a given day, against under 5% in February to September, the lowest months. Those are among Dhaka's driest months, with about 80 mm of rain a month against 440 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.
2nd of 19
Of the 19 cities where we can rate Chiasmia emersaria sightings, Dhaka ranks 2nd at about 20%. The best odds are in Jamshedpur (India, about 30%).
Same order: Lepidoptera
The closest relatives of the Chiasmia emersaria that you can see in Dhaka (order Lepidoptera, Butterflies and Moths) are Common Evening Brown (about 40%), Grey Pansy (about 40%) and Common Pierrot (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chiasmia emersaria is recorded against all the insects logged in Dhaka (13 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.
