Cercopis sanguinolenta is a species of froghopper in the family Cercopidae. This species mainly occurs in southern Europe up to Caucasus and the Near East. These froghoppers inhabit dry, sunny slopes and herbaceous rich clearings.
Cercopis sanguinolenta can reach a length of 6–11 millimetres (0.24–0.43 in). The male is larger than the female. These froghopper are shining black with bright red marks on the elytra, one spot at the base, one spot in the middle and a stripe at the apex.
Bodies in dorsal view are elongated and ovoid. The head is much narrower than the pronotum. Legs are always completely black. Very rarely, red marks are reduced or even missing, and such specimens are almost completely black. The adults of Cercopis, just after getting free from the nymphal exuvia, show pink or whitish markings instead of blood-red.
This species is very similar to Cercopis vulnerata, but its red stripes are smaller and the rear stripe is only slightly curved, while in Cercopis vulnerata it is U-shaped. Cercopis sanguinolenta also has a few black spots on the ventral plates of the connexivum, the lateral border of the abdomen. Wikipedia →

Rare
Under 5% of wildlife watchers report a Cercopis sanguinolenta sighting in Vienna on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 495th most-seen of the 1406 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April and May
In those months about 10% of wildlife watchers report a Cercopis sanguinolenta in Vienna on a given day, against under 5% in June to March, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Cercopis sanguinolenta sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 cities where we can rate Cercopis sanguinolenta sightings, Vienna ranks 2nd at under 5%. The best odds are in Prague (Czechia, about 10%).
GBIF citizen-science records
It is estimated from how often the Cercopis sanguinolenta is recorded against all the insects logged in Vienna (25 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.
