Rare
Under 5% of wildlife watchers report a Rusty Dot Pearl sighting in Kruger National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 656th 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.
August
In that month about 10% of wildlife watchers report a Rusty Dot Pearl in Kruger National Park on a given day, against under 5% in September to July, the lowest months. That is one of Kruger National Park's driest months, with almost no rain against 110 mm in February.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Rusty Dot 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.
8th of 9
Of the 9 parks where we can rate Rusty Dot Pearl sightings, Kruger National Park ranks 8th at under 5%. The best odds are in Addo Elephant National Park (South Africa, about 10%), Pyrénées National Park (France, about 10%) and Cévennes National Park (France, about 10%).

GBIF citizen-science records
It is estimated from how often the Rusty Dot Pearl is recorded against all the insects logged in Kruger National Park (5 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.
