Rare
Under 5% of wildlife watchers report an Amerila astreus sighting in Taipei on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 650th 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 an Amerila astreus in Taipei on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Amerila astreus sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 cities where we can rate Amerila astreus sightings, Taipei ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Kochi (India, under 5%).
Same family: Erebidae
The closest relatives of the Amerila astreus that you can see in Taipei (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Asota heliconia (about 20%), Chrysaeglia magnifica (about 20%) and Banyan Tussock Moth (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Amerila astreus is recorded against all the insects logged in Taipei (6 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.
