Possible
About 20% of wildlife watchers report a Derby's Flower Beetle sighting in Johannesburg on a given day, based on 66 verified sightings from GBIF citizen-science data. It is the 13th most-seen of the 213 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January
In that month about 40% of wildlife watchers report a Derby's Flower Beetle in Johannesburg on a given day, against under 5% in May to November, the lowest months. That is one of Johannesburg's wettest months, with about 120 mm of rain against almost none in July.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Derby's Flower Beetle sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Derby's Flower Beetle sightings, Johannesburg ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Pretoria (South Africa, about 20%).
Same family: Scarabaeidae

GBIF citizen-science records
It is estimated from how often the Derby's Flower Beetle is recorded against all the insects logged in Johannesburg (66 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.
