Rare
Under 5% of wildlife watchers report a Rusty Dot Pearl sighting in Table Mountain National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 219th most-seen of the 344 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Rusty Dot Pearl in Table Mountain National Park on a given day, so our monthly data shows no clear season.
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.
9th of 9
Of the 9 parks where we can rate Rusty Dot Pearl sightings, Table Mountain National Park ranks 9th 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 Table Mountain National Park (9 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.
