Cicadella viridis, sometimes called the "green leafhopper" (but not to be confused with Nephotettix a genus that includes rice pests), is a species of European leafhoppers belonging to the subfamily Cicadellinae. This species is present in most of Europe, in eastern Palearctic realm, in the Near East, in the Nearctic realm, and in the Indomalayan realm.
These leafhoppers inhabit rough grassy areas, peat bogs and mires, wet meadows, near marshes or in swampy habitats, but sometimes live also in drier areas. The adult males of Cicadella viridis can reach a length of 5.7–7 millimetres (0.22–0.28 in), but the females are quite larger than the males, reaching 7.5–9 millimetres (0.30–0.35 in).
Their pronotum and scutellum are green and yellow. The front head is pale yellow, with two black spots near the compound eyes. The forewings are turquoise green in the females, blue or dark bluish in males (sexual dimorphism). The abdomen is bluish-black.
The larvae are yellowish and have two brownish stripes running from head to the end of the abdomen. Adult leafhoppers can mostly be encountered from July through October. These leafhoppers... Wikipedia →

With luck
About 10% of wildlife watchers report a Green Leafhopper sighting in Brussels on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 200th 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 30%, if each day is a fresh chance.
June to September
In those months about 10% of wildlife watchers report a Green Leafhopper in Brussels on a given day, against under 5% in October to May, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Green Leafhopper sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 25 cities where we can rate Green Leafhopper sightings, Brussels ranks 8th at about 10%, level with the leaders once rounded. The best odds are in Manchester (United Kingdom, about 10%), Porto (Portugal, about 10%) and Turin (Italy, about 10%).
GBIF citizen-science records
It is estimated from how often the Green Leafhopper is recorded against all the insects logged in Brussels (10 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.
