With luck
About 10% of wildlife watchers report a September Fly sighting in Cape Town on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 90th most-seen of the 311 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
February–March and September–October
In those months about 10% of wildlife watchers report a September Fly in Cape Town on a given day, against under 5% in April–August and November–January, the lowest months.
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, Cape Town ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Pretoria (South Africa, about 10%) and Johannesburg (South Africa, about 10%).
Same order: Diptera
The closest relatives of the September Fly that you can see in Cape Town (order Diptera, Flies) are Common Drone Fly (about 10%), Stripe-Eyed Lagoon Fly (about 10%) and Episyrphus trisectus (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the September Fly is recorded against all the insects logged in Cape Town (39 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.
