Rare
Under 5% of wildlife watchers report a Simple-Eyed Lagoon Fly sighting in Cape Town on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 174th most-seen of the 311 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report a Simple-Eyed Lagoon Fly in Cape Town on a given day, against under 5% in October to August, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Simple-Eyed Lagoon Fly sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Cape Town, in our data
Cape Town is the only city on Wallace's Line with enough records to rate Simple-Eyed Lagoon Fly sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Eristalinus
The closest relatives of the Simple-Eyed Lagoon Fly that you can see in Cape Town (genus Eristalinus, Lagoon Flies) are Stripe-Eyed Lagoon Fly (about 10%) and Eristalinus barclayi (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Simple-Eyed Lagoon Fly is recorded against all the insects logged in Cape Town (16 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.
