Rhodometra sacraria, the vestal, is a moth of the family Geometridae. The species was first described by Carl Linnaeus in his 1767 12th edition of Systema Naturae. It can be found throughout Europe, in the Near East, in North Africa, in the Afrotropical realm and in large parts of Asia. It is also found in South America (Chile and Argentina).
Rhodometra sacraria inhabits meadows, forest clearing, paths, gardens and urban environments. Rhodometra sacraria has a wingspan reaching 22–28 mm, while the length of the forewings is 12–14 mm. The late generations are smaller and the wingspan has an average of 16–26 mm. These moths are easily distinguishable from the mahogany or pink stripe, located on yellowish or cream background, crossing diagonally the dorsal sides of the upperwings from the posterior margin up to the apex. Discal spots are usually present and have the same colour as the postmedial line.
The dorsal sides of the hindwings are whitish and unmarked. The fringes on the wings are mostly in the basic colour. The abdomen is pure white. Head and thorax are straw yellow. In males the antennae are bipectinated to three-fourths length... Wikipedia →

Possible
About 20% of wildlife watchers report a Vestal sighting in Barcelona on a given day, based on 127 verified sightings from GBIF citizen-science data. It is the 19th most-seen of the 381 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
September and October
In those months about 40% of wildlife watchers report a Vestal in Barcelona on a given day, against under 5% in December to July, the lowest months. Those are among Barcelona's wettest months, with about 85 mm of rain a month against 35 mm in December.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Vestal 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.
8th of 25
Of the 25 cities where we can rate Vestal sightings, Barcelona ranks 8th at about 20%. The best odds are in Valencia (Spain, about 50%), Kuwait City (Kuwait, about 20%) and Algiers (Algeria, about 20%).
Same family: Geometridae
The closest relatives of the Vestal that you can see in Barcelona (family Geometridae, Geometer Moths) are Double-Striped Pug (about 10%) and Small Dusty Wave (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Vestal is recorded against all the insects logged in Barcelona (127 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.
