With luck
About 10% of wildlife watchers report a Four Pearls sighting in Johannesburg on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 139th most-seen of the 213 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
September–October and December–February
In those months about 10% of wildlife watchers report a Four Pearls in Johannesburg on a given day, against under 5% in March–August and November, the lowest months. Those are among Johannesburg's wettest months, with about 80 mm of rain a month against almost none in July.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Four Pearls sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 2 cities where we can rate Four Pearls sightings, Johannesburg ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Nairobi (Kenya, about 10%).
Same family: Crambidae
The closest relatives of the Four Pearls that you can see in Johannesburg (family Crambidae, Crambid Snout Moths) are Hawaiian Beet Webworm Moth (about 10%), Black Wedge Pyralis (about 10%) and Dotted Sable (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Four Pearls is recorded against all the insects logged in Johannesburg (8 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.
