With luck
About 10% of wildlife watchers report a Spotted Sailer sighting in Nairobi on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 44th most-seen of the 123 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 and October
In those months about 20% of wildlife watchers report a Spotted Sailer in Nairobi on a given day, against under 5% in February–March, May and November, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Spotted Sailer sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 cities where we can rate Spotted Sailer sightings, Nairobi has the highest daily chance: about 10%. Next come Durban (South Africa, about 10%) and Lusaka (Zambia, about 10%).
Same family: Nymphalidae
The closest relatives of the Spotted Sailer that you can see in Nairobi (family Nymphalidae, Brush-footed Butterflies) are Soldier Commodore (about 30%), Yellow Pansy (about 30%) and Danaid Eggfly (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Spotted Sailer is recorded against all the insects logged in Nairobi (12 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.
