Rare
Under 5% of wildlife watchers report a Betasyrphus adligatus sighting in Cape Town on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 198th 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.
August and September
In those months about 10% of wildlife watchers report a Betasyrphus adligatus in Cape Town on a given day, against under 5% in October to July, the lowest months. Those are among Cape Town's wettest months, with about 90 mm of rain a month against 15 mm in February.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Betasyrphus adligatus sightings with a recorded time, and nearly all 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 Betasyrphus adligatus sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Syrphidae
The closest relatives of the Betasyrphus adligatus that you can see in Cape Town (family Syrphidae, Hover 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 Betasyrphus adligatus is recorded against all the insects logged in Cape Town (15 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.
