Possible
About 20% of wildlife watchers report an African Joker sighting in Gorongosa National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 21st most-seen of the 41 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
March and December
In those months about 40% of wildlife watchers report an African Joker in Gorongosa National Park on a given day, against under 5% in May–June, August–September and November, the lowest months. Those are among Gorongosa National Park's wettest months, with about 180 mm of rain a month against 15 mm in May.
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.
2nd of 5
Of the 5 parks where we can rate African Joker sightings, Gorongosa National Park ranks 2nd at about 20%. The best odds are in Ankarafantsika National Park (Madagascar, about 40%).
Same family: Nymphalidae
The closest relatives of the African Joker that you can see in Gorongosa National Park (family Nymphalidae, Brush-footed Butterflies) are Gold-Banded Forester (about 30%), Mycalesis rhacotis (about 30%) and Dancing Amber (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the African Joker is recorded against all the insects logged in Gorongosa National Park (6 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.
