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.

With luck
About 10% of wildlife watchers report a Common Froghopper sighting in Brussels on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 134th most-seen of the 337 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May
In that month about 20% of wildlife watchers report a Common Froghopper in Brussels on a given day, against under 5% in July to March, 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.
Among the best
Of the 21 cities where we can rate Common Froghopper sightings, Brussels ranks 10th at about 10%, level with the leaders once rounded. The best odds are in Turin (Italy, about 10%), Hamburg (Germany, about 10%) and Manchester (United Kingdom, about 10%).
Same order: Hemiptera
The closest relatives of the Common Froghopper that you can see in Brussels (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are European Firebug (about 30%), Southern Green Stink Bug (about 20%) and Dock Bug (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Froghopper is recorded against all the insects logged in Brussels (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.
