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 →

Rare
Under 5% of wildlife watchers report a Rhodostrophia calabra sighting in Pyrénées National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 1144th most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report a Rhodostrophia calabra in Pyrénées National Park on a given day, against under 5% in July to May, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Rhodostrophia calabra sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
4th of 4
Of the 4 parks where we can rate Rhodostrophia calabra sightings, Pyrénées National Park ranks 4th at under 5%. The best odds are in Cévennes National Park (France, about 10%), Sierra Nevada National Park (Spain, about 10%) and Sierra de Guadarrama National Park (Spain, about 10%).
GBIF citizen-science records
It is estimated from how often the Rhodostrophia calabra is recorded against all the insects logged in Pyrénées National Park (7 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.
