With luck
About 10% of wildlife watchers report a Yellow Underwing sighting in Chennai on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 188th most-seen of the 376 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.
July–October and December–January
In those months about 10% of wildlife watchers report a Yellow Underwing in Chennai on a given day, against under 5% in February–June and November, 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.
Among the best
Of the 12 cities where we can rate Yellow Underwing sightings, Chennai ranks 5th 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 Chennai (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Sandalwood Defoliator (about 30%), Dot-Underwing Moth (about 20%) and Common Fruit-Piercing 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 Chennai (12 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.
