Stemorrhages sericea
In 3 days ~10% in a week ~20%
Stemorrhages sericea, the large emerald pearl, is a moth of the subfamily of Spilomelinae within the family Crambidae. It lives throughout Africa south of the Sahara, and the Indian Ocean islands of Réunion, Madagascar, Mauritius and the Comoros.
Adults are pale turquoise with a brown stripe at the front edge of the wings. They have a brush of brown scent disseminating scales, called androconia, on the tail that can be everted for mate attraction. The larvae feed on species of the Rubiaceae (including Gardenia jasminoides), the Apocynaceae (including Nerium oleander, Tabernanthe iboga, Tabernaemontana persicaefolia and Ervatamia coronaria), and besides on Raphia and Afrocarpus.

Rare
Under 5% of wildlife watchers report a Large Emerald Pearl sighting in Kruger National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 472nd most-seen of the 748 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.
May and July
In those months about 10% of wildlife watchers report a Large Emerald Pearl in Kruger National Park on a given day, against under 5% in June and August–April, the lowest months. Those are among Kruger National Park's driest months, with about 10 mm of rain a month against 110 mm in February.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Large Emerald Pearl sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Kruger National Park, in our data
Kruger National Park is the only park on Wallace's Line with enough records to rate Large Emerald Pearl sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Crambidae
The closest relatives of the Large Emerald Pearl that you can see in Kruger National Park (family Crambidae, Crambid Snout Moths) are Jasmine Moth (about 10%), Hawaiian Beet Webworm Moth (about 10%) and Measured Pearl (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Large Emerald Pearl is recorded against all the insects logged in Kruger National Park (8 verified sightings from 2019 to 2026), 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.
