Rare
Under 5% of wildlife watchers report a Chiasmia emersaria sighting in Bangkok on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 173rd most-seen of the 245 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
July and December–January
In those months about 10% of wildlife watchers report a Chiasmia emersaria in Bangkok on a given day, against under 5% in February–June and August–November, the lowest months. Those are among Bangkok's driest months, with about 65 mm of rain a month against 280 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.
17th of 19
Of the 19 cities where we can rate Chiasmia emersaria sightings, Bangkok ranks 17th at under 5%. 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 Bangkok (8 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.
