Oryctes monoceros
In 3 days ~60% in a week ~90%
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.

Possible
About 30% of wildlife watchers report an African Rhinoceros Beetle sighting in Maputo on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 5th most-seen of the 8 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
November
In that month about 50% of wildlife watchers report an African Rhinoceros Beetle in Maputo on a given day, against under 5% in March–April, July, October and December–January, the lowest months. That is one of Maputo's wettest months, with about 100 mm of rain against 15 mm 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.
Yes
Of the 2 cities where we can rate African Rhinoceros Beetle sightings, Maputo has the highest daily chance: about 30%. Next come Durban (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 Maputo (6 verified sightings), 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.
