With luck
About 10% of wildlife watchers report a Yellow Underwing sighting in Tainan on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 81st most-seen of the 97 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
November
In that month about 20% of wildlife watchers report a Yellow Underwing in Tainan on a given day, against under 5% in July–August, October and December–May, the lowest months. That is one of Tainan's driest months, with about 50 mm of rain against 440 mm in August.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellow Underwing sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 12 cities where we can rate Yellow Underwing sightings, Tainan ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Thrissur (India, about 10%), Kochi (India, about 10%) and Kolkata (India, about 10%).
Same family: Erebidae
The closest relatives of the Yellow Underwing that you can see in Tainan (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Cocoa Tussock Moth (about 10%), Brown Tussock Moth (about 10%) and Taiwan Yellow Tussock Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Yellow Underwing is recorded against all the insects logged in Tainan (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.
