With luck
About 10% of wildlife watchers report a Measured Pearl sighting in Johannesburg on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 110th most-seen of the 213 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
March
In that month about 20% of wildlife watchers report a Measured Pearl in Johannesburg on a given day, against under 5% in February, May–August, October and December, the lowest months.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Measured Pearl sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Among the best
Of the 7 cities where we can rate Measured Pearl sightings, Johannesburg ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Harare (Zimbabwe, about 10%) and Pretoria (South Africa, about 10%).
Same family: Crambidae
The closest relatives of the Measured Pearl 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 Measured Pearl is recorded against all the insects logged in Johannesburg (13 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.
