With luck
About 10% of wildlife watchers report a Scarlet Adjutant sighting in Kolkata on a given day, based on 30 verified sightings from GBIF citizen-science data. It is the 74th most-seen of the 213 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
September
In that month about 30% of wildlife watchers report a Scarlet Adjutant in Kolkata on a given day, against under 5% in January–February, May and November, the lowest months. That is one of Kolkata's wettest months, with about 260 mm of rain against 10 mm in December.
Between 1 and 4 am
Across all the parks we cover, that three-hour window holds the most Scarlet Adjutant sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
7th of 13
Of the 13 cities where we can rate Scarlet Adjutant sightings, Kolkata ranks 7th at about 10%. The best odds are in Thiruvananthapuram (India, about 30%), Thrissur (India, about 20%) and Kochi (India, about 20%).
Same family: Libellulidae
The closest relatives of the Scarlet Adjutant that you can see in Kolkata (family Libellulidae, Skimmers) are Scarlet Skimmer (about 40%), Ditch Jewel (about 40%) and Pied Paddy Skimmer (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Scarlet Adjutant is recorded against all the insects logged in Kolkata (30 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.
