Rare
Under 5% of wildlife watchers report a Yellow Underwing sighting in Singapore on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 638th most-seen of the 1045 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
In that month about 10% of wildlife watchers report a Yellow Underwing in Singapore on a given day, against under 5% in August to June, the lowest months.
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.
12th of 12
Of the 12 cities where we can rate Yellow Underwing sightings, Singapore ranks 12th 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 Singapore (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Hübner's Wasp Moth (about 30%), Triangular-Striped Moth (about 10%) and Erebus ephesperis (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 Singapore (14 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.
