Rare
Under 5% of wildlife watchers report a Brooklet Milkweed Bug sighting in Durban on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 345th most-seen of the 401 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 and March
In those months about 10% of wildlife watchers report a Brooklet Milkweed Bug in Durban on a given day, against under 5% in February and April–December, the lowest months. Those are among Durban's wettest months, with about 180 mm of rain a month against 25 mm in June.
3rd of 3
Of the 3 cities where we can rate Brooklet Milkweed Bug sightings, Durban ranks 3rd at under 5%. The best odds are in Pretoria (South Africa, about 10%) and Johannesburg (South Africa, about 10%).
GBIF citizen-science records
It is estimated from how often the Brooklet Milkweed Bug is recorded against all the insects logged in Durban (5 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.
