Rare
Under 5% of wildlife watchers report an Eristalinus barclayi sighting in Table Mountain National Park on a given day, based on 40 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 114th most-seen of the 344 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.
April–May and December–January
In those months about 10% of wildlife watchers report an Eristalinus barclayi in Table Mountain National Park on a given day, against under 5% in February–March and June–November, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Eristalinus barclayi sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Table Mountain National Park, in our data
Table Mountain National Park is the only park on Wallace's Line with enough records to rate Eristalinus barclayi sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Eristalinus barclayi is recorded against all the insects logged in Table Mountain National Park (40 verified sightings from 2019 to 2026), 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.
