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 →

August
In that month about 20% of wildlife watchers report a Green Leafhopper in Birmingham on a given day, against under 5% in October to June, the lowest months.

GBIF citizen-science records
It is estimated from how often the Green Leafhopper is recorded against all the insects logged in Birmingham (33 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.
