With luck
About 10% of wildlife watchers report an Orange Naked Pearl sighting in Sierra Nevada National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 390th most-seen of the 479 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report an Orange Naked Pearl in Sierra Nevada National Park on a given day, against under 5% in October to May, the lowest months. That is one of Sierra Nevada National Park's driest months, with about 30 mm of rain against 130 mm in March.
Between 5 and 8 pm
Across all the parks we cover, that three-hour window holds the most Orange Naked Pearl 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.
Yes
Of the 2 parks where we can rate Orange Naked Pearl sightings, Sierra Nevada National Park has the highest daily chance: about 10%. Next come Camargue (France, about 10%).

GBIF citizen-science records
It is estimated from how often the Orange Naked Pearl is recorded against all the insects logged in Sierra Nevada 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.
