Cercopis vulnerata (also known as the black-and-red froghopper or red-and-black froghopper) is a species of froghopper in the family Cercopidae. This species is present in most of Europe (Albania, Austria, Belgium, Bulgaria, Serbia, Croatia, Czech Republic, France, Greece, Spain, the former Yugoslavia, Moldova, the Netherlands, Norway, Poland, Romania, Russia, Slovakia, Slovenia, Germany, Switzerland, Hungary, Great Britain and Italy).
These froghoppers inhabit sunny southern slopes of the mountains, grasslands, meadows, spruce forest edges, moors, verges, clearings and city parks. They can be found on woody or herbaceous plants, mainly in wooded areas.
The male of Cercopis vulnerata is 8.9–10.5 millimetres (0.35–0.41 in) in length, and the female 8.2–10.5 millimetres (0.32–0.41 in). These froghoppers have an elongate and strongly shielded body. They are shining black, with bright red marks on the elytra, one triangular mark at the base, one square mark in the middle and a stripe at the apex. These colors serves as a warning of their unpleasant taste.
The hind wings are brownish, smoky and translucent. Upper abdomen is black with narrow... Wikipedia →

Rare
Under 5% of wildlife watchers report a Common Froghopper sighting in Prague on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 330th most-seen of the 724 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.
May and June
In those months about 10% of wildlife watchers report a Common Froghopper in Prague on a given day, against under 5% in July to April, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Common Froghopper sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
18th of 21
Of the 21 cities where we can rate Common Froghopper sightings, Prague ranks 18th at under 5%. The best odds are in Turin (Italy, about 10%), Hamburg (Germany, about 10%) and Manchester (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Common Froghopper is recorded against all the insects logged in Prague (15 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.
