With luck
About 10% of wildlife watchers report a Narrow-Winged Grey sighting in Madrid on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 148th most-seen of the 457 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
February–April and October–November
In those months about 10% of wildlife watchers report a Narrow-Winged Grey in Madrid on a given day, against under 5% in May–September and December–January, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Narrow-Winged Grey sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 10 cities where we can rate Narrow-Winged Grey sightings, Madrid ranks 8th at about 10%, level with the leaders once rounded. The best odds are in Porto (Portugal, about 10%), Rome (Italy, about 10%) and London (United Kingdom, about 10%).
Same family: Crambidae
The closest relatives of the Narrow-Winged Grey that you can see in Madrid (family Crambidae, Crambid Snout Moths) are Rush Veneer (about 20%), Wandering Sunset (about 10%) and Jasmine Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Narrow-Winged Grey is recorded against all the insects logged in Madrid (27 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.
