Uresiphita gilvata is a moth of the family Crambidae. It was first described by Johan Christian Fabricius in 1794 and is found in Europe and North Africa. The wingspan is 29–37 mm. The forewing is greyish to light brown sometimes whitish bands either side of the median area (sometimes obsolete). The hindwing is pale or bright yellow with a black margin. The lines vary from faint to clear. The postmedian line is undulating and the antemedian line is almost straight.
Adults are on wing from September to October depending on the location. The larvae feed on various low-growing herbaceous plants, including Genista, Cytisus and Ulex. It is listed as a synonym of Uresiphita polygonalis by some sources. Wikipedia →

With luck
About 10% of wildlife watchers report a Wandering Sunset sighting in Barcelona on a given day, based on 52 verified sightings from GBIF citizen-science data. It is the 70th most-seen of the 381 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
April and June
In those months about 20% of wildlife watchers report a Wandering Sunset in Barcelona on a given day, against under 5% in January and August, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Wandering Sunset sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 9 cities where we can rate Wandering Sunset sightings, Barcelona ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Jerusalem (Israel, about 10%), Madrid (Spain, about 10%) and Valencia (Spain, about 10%).
Same family: Crambidae
The closest relatives of the Wandering Sunset that you can see in Barcelona (family Crambidae, Crambid Snout Moths) are Rush Veneer (about 10%), Hawaiian Beet Webworm Moth (about 10%) and Sesame Leafroller (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Wandering Sunset is recorded against all the insects logged in Barcelona (52 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.
