With luck
About 10% of wildlife watchers report a Black Looper sighting in Pune on a given day, based on 40 verified sightings from GBIF citizen-science data. It is the 79th most-seen of the 340 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
July and August
In those months about 20% of wildlife watchers report a Black Looper in Pune on a given day, against under 5% in May, the lowest month. Those are among Pune's wettest months, with about 460 mm of rain a month against almost none in January.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Black Looper sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 11 cities where we can rate Black Looper sightings, Pune ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Tuen Mun (China, about 10%) and Hong Kong (China, about 10%).
Same family: Geometridae
The closest relatives of the Black Looper that you can see in Pune (family Geometridae, Geometer Moths) are Acacia Blood Vein Moth (about 20%), Chiasmia emersaria (about 10%) and Idaea macrospila (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black Looper is recorded against all the insects logged in Pune (40 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.
