Hagenomyia tristis
In 3 days ~70% in a week ~90%
Hagenomyia tristis is an African antlion species. It is known as the gregarious antlion as it is often found in swarms in long grass in the shade of trees. The range of this species extends from eastern South Africa to Cameroon and Ethiopia; it is also found in Madagascar. The larvae build sand pit traps to capture prey. This species is believed to be the mimic of Banyutus lethalis, with both species commonly swarming together. Wikipedia →

Possible
About 30% of wildlife watchers report a Gregarious Antlion sighting in Waterberg Plateau Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 24 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
February and March
In those months about 70% of wildlife watchers report a Gregarious Antlion in Waterberg Plateau Park on a given day, against under 5% in August and November, the lowest months. Those are among Waterberg Plateau Park's wettest months, with about 75 mm of rain a month against almost none in May.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Gregarious Antlion sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 parks where we can rate Gregarious Antlion sightings, Waterberg Plateau Park has the highest daily chance: about 30%. Next come Kruger National Park (South Africa, about 10%).
GBIF citizen-science records
It is estimated from how often the Gregarious Antlion is recorded against all the insects logged in Waterberg Plateau Park (5 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.
