Rare
Under 5% of wildlife watchers report a Phostria bistigmalis 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.
April and December–January
In those months about 10% of wildlife watchers report a Phostria bistigmalis in Kruger National Park on a given day, against under 5% in February–March and May–November, the lowest months. Those are among Kruger National Park's wettest months, with about 70 mm of rain a month against almost none in August.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Phostria bistigmalis 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.
Only Kruger National Park, in our data
Kruger National Park is the only park on Wallace's Line with enough records to rate Phostria bistigmalis sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Crambidae
The closest relatives of the Phostria bistigmalis 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 Phostria bistigmalis 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.
