With luck
About 10% of wildlife watchers report a The Passenger sighting in Sierra Nevada National Park on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 147th most-seen of the 479 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
June to August
In those months about 20% of wildlife watchers report a The Passenger in Sierra Nevada National Park on a given day, against under 5% in October to April, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most The Passenger sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 4 parks where we can rate The Passenger sightings, Sierra Nevada National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Cévennes National Park (France, about 10%).
Same family: Erebidae
The closest relatives of the The Passenger that you can see in Sierra Nevada National Park (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Drasteria cailino (about 20%), Discrete Chaperon (about 20%) and Speckled Footman (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the The Passenger is recorded against all the insects logged in Sierra Nevada National Park (19 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.
