Rare
Under 5% of wildlife watchers report an Angled Pierrot sighting in Pune on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 225th most-seen of the 340 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.
September–October and December–February
In those months about 10% of wildlife watchers report an Angled Pierrot in Pune on a given day, against under 5% in March–August and November, the lowest months. Those are among Pune's driest months, with about 75 mm of rain a month against 520 mm in July.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Angled Pierrot sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 cities where we can rate Angled Pierrot sightings, Pune ranks 2nd at under 5%. The best odds are in Mumbai (India, about 10%).
Same family: Lycaenidae
The closest relatives of the Angled Pierrot that you can see in Pune (family Lycaenidae, Gossamer-winged Butterflies) are Red Pierrot (about 40%), Zebra Blue (about 30%) and Plains Cupid (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Angled Pierrot is recorded against all the insects logged in Pune (10 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.
