Rare
Under 5% of wildlife watchers report a Chiasmia emersaria sighting in Taipei on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 703rd most-seen of the 765 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Chiasmia emersaria in Taipei on a given day, so our monthly data shows no clear season.
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.
19th of 19
Of the 19 cities where we can rate Chiasmia emersaria sightings, Taipei ranks 19th at under 5%. The best odds are in Jamshedpur (India, about 30%), Dhaka (Bangladesh, about 20%) and Jabalpur (India, about 20%).
Same family: Geometridae
The closest relatives of the Chiasmia emersaria that you can see in Taipei (family Geometridae, Geometer Moths) are Milionia basalis (about 20%), Eumelea ludovicata (about 10%) and Asian Cross-Lined Wave Moth (about 10%), 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 Taipei (5 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.
