Possible
About 30% of wildlife watchers report a Common Sailer sighting in Jabalpur on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 24th most-seen of the 88 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
January–February and October
In those months about 50% of wildlife watchers report a Common Sailer in Jabalpur on a given day, against under 5% in March and May–August, the lowest months. Those are among Jabalpur's driest months, with about 25 mm of rain a month against 410 mm in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Common Sailer sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 35 cities where we can rate Common Sailer sightings, Jabalpur ranks 2nd at about 30%, level with the leaders once rounded. The best odds are in Salem (India, about 30%).
Same family: Nymphalidae
The closest relatives of the Common Sailer that you can see in Jabalpur (family Nymphalidae, Brush-footed Butterflies) are Great Eggfly (about 40%), Plain Tiger Butterfly (about 40%) and Common Crow (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Sailer is recorded against all the insects logged in Jabalpur (14 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.
