With luck
About 10% of wildlife watchers report a Spotted Sailer sighting in Durban on a given day, based on 67 verified sightings from GBIF citizen-science data. It is the 29th most-seen of the 401 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.
June
In that month about 30% of wildlife watchers report a Spotted Sailer in Durban on a given day, against under 5% in February, October and December, the lowest months. That is one of Durban's driest months, with about 25 mm of rain against 210 mm in January.
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.
Among the best
Of the 4 cities where we can rate Spotted Sailer sightings, Durban ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Nairobi (Kenya, about 10%).
GBIF citizen-science records
It is estimated from how often the Spotted Sailer is recorded against all the insects logged in Durban (67 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.
