With luck
About 10% of wildlife watchers report a Crimson Rose Swallowtail sighting in Kochi on a given day, based on 35 verified sightings from GBIF citizen-science data. It is the 127th most-seen of the 428 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
April
In that month about 20% of wildlife watchers report a Crimson Rose Swallowtail in Kochi on a given day, against under 5% in June and December, the lowest months. That is one of Kochi's driest months, with about 130 mm of rain against 490 mm in June.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Crimson Rose Swallowtail sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
11th of 13
Of the 13 cities where we can rate Crimson Rose Swallowtail sightings, Kochi ranks 11th at about 10%. The best odds are in Madurai (India, about 30%), Coimbatore (India, about 20%) and Chennai (India, about 20%).
GBIF citizen-science records
It is estimated from how often the Crimson Rose Swallowtail is recorded against all the insects logged in Kochi (35 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.
