Rare
Under 5% of wildlife watchers report a Derby's Flower Beetle sighting in Cape Town on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 208th most-seen of the 311 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.
January to March
In those months about 10% of wildlife watchers report a Derby's Flower Beetle in Cape Town on a given day, against under 5% in April to December, the lowest months. Those are among Cape Town's driest months, with about 20 mm of rain a month against 140 mm in June.

GBIF citizen-science records
It is estimated from how often the Derby's Flower Beetle is recorded against all the insects logged in Cape Town (10 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.
