With luck
About 10% of wildlife watchers report a The Passenger sighting in Budapest on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 168th most-seen of the 404 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.
August
In that month about 20% of wildlife watchers report a The Passenger in Budapest on a given day, against under 5% in October to May, 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 11 cities where we can rate The Passenger sightings, Budapest ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Porto (Portugal, about 10%) and Turin (Italy, about 10%).
Same family: Erebidae
The closest relatives of the The Passenger that you can see in Budapest (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Four-Spotted Moth (about 20%), Nine-Spotted Moth (about 10%) and Red Underwing (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 Budapest (14 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.
