The adult males can reach a body length (from front to elytral apex) of about 12.1 millimetres (0.48 in), while females are bigger, reaching a size of about 13.1 millimetres (0.52 in). The body is usually bright green and shield-shaped and the eyes are most commonly reddish, but they may also be black. There is a row of three white spots on the scutellum. They... Wikipedia →

With luck
About 10% of wildlife watchers report a Southern Green Stink Bug sighting in Johannesburg on a given day, based on 35 verified sightings from GBIF citizen-science data. It is the 34th most-seen of the 213 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
April–May and September

GBIF citizen-science records
It is estimated from how often the Southern Green Stink Bug is recorded against all the insects logged in Johannesburg (35 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.
