Rare
Under 5% of wildlife watchers report a Brunia antica sighting in Chennai on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 298th most-seen of the 376 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.
October to January
In those months about 10% of wildlife watchers report a Brunia antica in Chennai on a given day, against under 5% in February to September, the lowest months. Those are among Chennai's wettest months, with about 170 mm of rain a month against 5 mm in February.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Brunia antica sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
6th of 8
Of the 8 cities where we can rate Brunia antica sightings, Chennai ranks 6th at under 5%. The best odds are in Hong Kong (China, about 10%), Tuen Mun (China, about 10%) and Pune (India, about 10%).
Same family: Erebidae
The closest relatives of the Brunia antica 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 Brunia antica is recorded against all the insects logged in Chennai (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.
