Rare
Under 5% of wildlife watchers report a The Passenger sighting in Istanbul on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 215th most-seen of the 266 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.
May–July and September
In those months about 10% of wildlife watchers report a The Passenger in Istanbul on a given day, against under 5% in August and October–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.
8th of 11
Of the 11 cities where we can rate The Passenger sightings, Istanbul ranks 8th at under 5%. The best odds are in Porto (Portugal, about 10%), Turin (Italy, about 10%) and Budapest (Hungary, about 10%).
Same family: Erebidae
The closest relatives of the The Passenger that you can see in Istanbul (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Fall Webworm Moth (about 10%), Four-Spotted Moth (about 10%) and Spongy Moth (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 Istanbul (6 verified sightings), 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.
