Rare
Under 5% of wildlife watchers report a Yellow Underwing sighting in Bangkok on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 137th 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 30%, if each day is a fresh chance.
June, August–September and November
In those months about 10% of wildlife watchers report a Yellow Underwing in Bangkok on a given day, against under 5% in July, October and December–May, the lowest months. Those are among Bangkok's wettest months, with about 170 mm of rain a month against 10 mm in December.
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.
11th of 12
Of the 12 cities where we can rate Yellow Underwing sightings, Bangkok ranks 11th at under 5%. 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 Bangkok (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Psichotoe duvauceli (about 10%) and Amata sperbius (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 Bangkok (11 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.
