Rare
Under 5% of wildlife watchers report a Purple-Edged Pearl 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.
April and July
In those months about 10% of wildlife watchers report a Purple-Edged Pearl in Durban on a given day, against under 5% in May–June and August–March, the lowest months. Those are among Durban's driest months, with about 60 mm of rain a month against 210 mm in January.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Purple-Edged Pearl sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Durban, in our data
Durban is the only city on Wallace's Line with enough records to rate Purple-Edged Pearl sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Crambidae
The closest relatives of the Purple-Edged Pearl that you can see in Durban (family Crambidae, Crambid Snout Moths) are Dotted Sable (about 10%), Hawaiian Beet Webworm Moth (about 10%) and Cucumber Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Purple-Edged Pearl 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.
