Rare
Under 5% of wildlife watchers report an African Joker sighting in Kruger National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 472nd 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 20%, if each day is a fresh chance.
May
In that month about 10% of wildlife watchers report an African Joker in Kruger National Park on a given day, against under 5% in June to April, the lowest months. That is one of Kruger National Park's driest months, with about 10 mm of rain against 110 mm in February.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most African Joker sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 5
Of the 5 parks where we can rate African Joker sightings, Kruger National Park ranks 5th at under 5%. The best odds are in Ankarafantsika National Park (Madagascar, about 40%), Gorongosa National Park (Mozambique, about 20%) and Chobe National Park (Botswana, about 10%).
GBIF citizen-science records
It is estimated from how often the African Joker is recorded against all the insects logged in Kruger National Park (8 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.
