Possible
About 30% of wildlife watchers report an Apple-Green Swallowtail sighting in Nairobi on a given day, based on 49 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 123 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
January and September
In those months about 40% of wildlife watchers report an Apple-Green Swallowtail in Nairobi on a given day, against about 20% in February, April–July and October–November, the lowest months. Those are among Nairobi's driest months, with about 35 mm of rain a month against 150 mm in April.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Apple-Green Swallowtail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Nairobi, in our data
Nairobi is the only city on Wallace's Line with enough records to rate Apple-Green Swallowtail sightings: about 30% of wildlife watchers there report one on a given day.
Same genus: Papilio
The closest relatives of the Apple-Green Swallowtail that you can see in Nairobi (genus Papilio, Common Swallowtails) are Mocker Swallowtail (about 30%), Citrus Swallowtail (about 30%) and Narrow Green-Banded Swallowtail (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Apple-Green Swallowtail is recorded against all the insects logged in Nairobi (49 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.
