With luck
About 10% of wildlife watchers report a Formosan Swift sighting in Pune on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 141st most-seen of the 340 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January, March, June and August–November
In those months about 10% of wildlife watchers report a Formosan Swift in Pune on a given day, against under 5% in February, April–May, July and December, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Formosan Swift sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
17th of 19
Of the 19 cities where we can rate Formosan Swift sightings, Pune ranks 17th at about 10%. The best odds are in Tuen Mun (China, about 20%), Jabalpur (India, about 20%) and Salem (India, about 10%).
Same family: Hesperiidae
The closest relatives of the Formosan Swift that you can see in Pune (family Hesperiidae, Skippers) are Grass Demon (about 20%), Indian Palm Bob (about 10%) and Common Banded Awl (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Formosan Swift is recorded against all the insects logged in Pune (20 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.
