With luck
About 10% of wildlife watchers report a September Fly sighting in Johannesburg on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 120th most-seen of the 213 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January
In that month about 20% of wildlife watchers report a September Fly in Johannesburg on a given day, against under 5% in February–August and October–December, the lowest months. That is one of Johannesburg's wettest months, with about 120 mm of rain against almost none in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most September Fly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 cities where we can rate September Fly sightings, Johannesburg ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Pretoria (South Africa, about 10%).
GBIF citizen-science records
It is estimated from how often the September Fly is recorded against all the insects logged in Johannesburg (11 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.
