With luck
About 10% of wildlife watchers report a Yellow Underwing sighting in Thrissur on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 79th most-seen of the 93 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Yellow Underwing in Thrissur on a given day, against under 5% in June and August–April, the lowest months. That is one of Thrissur's wettest months, with about 400 mm of rain against 10 mm in January.
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.
Yes
Of the 12 cities where we can rate Yellow Underwing sightings, Thrissur has the highest daily chance: about 10%. Next come Kochi (India, about 10%) and Kolkata (India, about 10%).
Same family: Erebidae
The closest relatives of the Yellow Underwing that you can see in Thrissur (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Tropical Tiger Moth (about 20%) and Dot-Underwing 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 Thrissur (5 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.
