Rare
Under 5% of wildlife watchers report an Episyrphus trisectus sighting in Durban on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 224th most-seen of the 401 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
January, April and July–October
In those months about 10% of wildlife watchers report an Episyrphus trisectus in Durban on a given day, against under 5% in February–March, May–June and November–December, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Episyrphus trisectus sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 cities where we can rate Episyrphus trisectus sightings, Durban ranks 4th at under 5%. The best odds are in Pretoria (South Africa, about 10%), Johannesburg (South Africa, about 10%) and Cape Town (South Africa, about 10%).
Same family: Syrphidae
The closest relatives of the Episyrphus trisectus that you can see in Durban (family Syrphidae, Hover Flies) are Green Jewel Fly (about 10%), Stripe-Eyed Lagoon Fly (about 10%) and Florida Calligrapher (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Episyrphus trisectus is recorded against all the insects logged in Durban (9 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.
