With luck
About 10% of wildlife watchers report a Twin Swift sighting in Kruger National Park on a given day, based on 23 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 207th most-seen of the 748 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
March–June and October
In those months about 10% of wildlife watchers report a Twin Swift in Kruger National Park on a given day, against under 5% in July–September and November–February, the lowest months. Those are among Kruger National Park's driest months, with about 20 mm of rain a month against 110 mm in February.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Twin Swift sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 parks where we can rate Twin Swift sightings, Kruger National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in iSimangaliso Wetland Park (South Africa, about 10%).
Same family: Hesperiidae
The closest relatives of the Twin Swift that you can see in Kruger National Park (family Hesperiidae, Skippers) are Striped Policeman (about 10%), Dark Elfin (about 10%) and Orange Elfin (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Twin Swift is recorded against all the insects logged in Kruger National Park (23 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.
