Rare
Under 5% of wildlife watchers report a Regal Blowfly sighting in Kruger National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 430th most-seen of the 748 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.
July and October
In those months about 10% of wildlife watchers report a Regal Blowfly in Kruger National Park on a given day, against under 5% in August–September and November–June, the lowest months. Those are among Kruger National Park's driest months, with about 15 mm of rain a month against 110 mm in February.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Regal Blowfly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Regal Blowfly sightings, Kruger National Park ranks 3rd at under 5%. The best odds are in Addo Elephant National Park (South Africa, about 10%) and iSimangaliso Wetland Park (South Africa, under 5%).
GBIF citizen-science records
It is estimated from how often the Regal Blowfly is recorded against all the insects logged in Kruger National Park (9 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.
