Oryctes monoceros
In 3 days ~10% in a week ~20%
Oryctes monoceros, commonly known as African rhinoceros beetle, is a species of rhinoceros beetles from the subfamily Dynastinae (family: Scarabaeidae) which is common in sub-Saharan Africa. Its distribution extends from Senegal and Chad in the North to South Africa in the South and includes the islands of Madagascar, Seychelles and Réunion in the East. O. monoceros is similar in size (~ 4 cm long) and biology to O. rhinoceros found in tropical parts of Asia and the Pacific. Both species are serious pests of coconut and oil palms and attack these by boring into the crown of the palms and feeding on the young developing fronds. Taxonomically, O. monoceros and O. rhinoceros belong to different subgenera of Oryctes, the main differences between both species are: Oryctes monoceros (subgenus Rykanoryctes) has 3 immovable spikes at the tip of the hindtibia and on average males have a shorter horn than O. rhinoceros which is more strongly curved backwards. Oryctes rhinoceros (subgenus Rykanes) has 2 immovable spikes at the tip of the hindtibia and on average males have a longer horn than in O. monoceros which is only slightly curved backwards.

Rare
Under 5% of wildlife watchers report an African Rhinoceros Beetle sighting in Kruger National Park on a given day, based on 10 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.
March and December
In those months about 10% of wildlife watchers report an African Rhinoceros Beetle in Kruger National Park on a given day, against under 5% in January–February and April–November, the lowest months. Those are among Kruger National Park's wettest months, with about 65 mm of rain a month against almost none in August.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most African Rhinoceros Beetle sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
2nd of 2
Of the 2 parks where we can rate African Rhinoceros Beetle sightings, Kruger National Park ranks 2nd at under 5%. The best odds are in iSimangaliso Wetland Park (South Africa, about 10%).
GBIF citizen-science records
It is estimated from how often the African Rhinoceros Beetle is recorded against all the insects logged in Kruger National Park (10 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.
