Rare
Under 5% of wildlife watchers report a Cinerous Pearl sighting in Bavarian Forest National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 964th most-seen of the 1115 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July
In that month about 10% of wildlife watchers report a Cinerous Pearl in Bavarian Forest National Park on a given day, against under 5% in August to June, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Cinerous 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 Bavarian Forest National Park, in our data
Bavarian Forest National Park is the only park on Wallace's Line with enough records to rate Cinerous Pearl sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Anania
The closest relatives of the Cinerous Pearl that you can see in Bavarian Forest National Park (genus Anania) are Small Magpie (about 10%), Golden Pearl (about 10%) and Long-Winged Pearl (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cinerous Pearl is recorded against all the insects logged in Bavarian Forest 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.
