Rare
Under 5% of wildlife watchers report a Perilla Leaf Moth sighting in Chennai on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 338th 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.
May and October–December
In those months about 10% of wildlife watchers report a Perilla Leaf Moth in Chennai on a given day, against under 5% in January–April and June–September, the lowest months. Those are among Chennai's wettest months, with about 180 mm of rain a month against 5 mm in February.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Perilla Leaf Moth sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
4th of 6
Of the 6 cities where we can rate Perilla Leaf Moth sightings, Chennai ranks 4th at under 5%. The best odds are in Jamshedpur (India, about 30%), Hyderabad (India, about 10%) and Pune (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Perilla Leaf Moth is recorded against all the insects logged in Chennai (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.
