Rhodostrophia calabra is a moth of the family Geometridae first described by Vincenzo Petagna in 1786. It is found from the Iberian Peninsula and a small isolated population in Morocco, through southern France, the western and southern Alps, Italy, the eastern coast of the Adriatic Sea to the southern parts of the Balkan Peninsula. In central Europe it is only found as an isolated population in central France and Rheinland-Pfalz. It is not found on the islands in the Mediterranean Sea (Corsica, Sardinia, the Balearic Islands, Sicily and Crete). In the Balkans there is an isolated population in the border region of northern Bulgaria and Serbia. Furthermore, it is present on the eastern shores of the Black Sea in Turkey and in the Caucasus.
The wingspan is 28–33 mm for males and 28–35 mm for females. The moths fly in one generation from May to June. The larvae feed on various Fabaceae species, including Cytisus scoparius, Genista (mainly Genista tinctoria), Dorycnium, Scabiosa, Rumex, Polygonum, Thymus and Asperula. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Rhodostrophia calabra is recorded against all the insects logged in Sierra de Guadarrama National Park (12 verified sightings from 2019 to 2026), 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.
