Rare
Under 5% of wildlife watchers report a Sulphur Ant-Heap White sighting in Kruger National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 290th 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.
May to July
In those months about 10% of wildlife watchers report a Sulphur Ant-Heap White in Kruger National Park on a given day, against under 5% in August to April, the lowest months. Those are among Kruger National Park's driest months, with about 10 mm of rain a month against 110 mm in February.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Sulphur Ant-Heap White 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 parks where we can rate Sulphur Ant-Heap White sightings, Kruger National Park ranks 4th at under 5%. The best odds are in uMkhuze Game Reserve (South Africa, about 20%), Hluhluwe-Imfolozi Park (South Africa, about 10%) and iSimangaliso Wetland Park (South Africa, about 10%).
GBIF citizen-science records
It is estimated from how often the Sulphur Ant-Heap White is recorded against all the insects logged in Kruger National Park (17 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.
