Metcalfa pruinosa, the citrus flatid planthopper, is a species of insect in the Flatidae family of planthoppers first described by Thomas Say in 1830. Metcalfa pruinosa cubana (Metcalf & Bruner, 1948) The species is native to North America (Nearctic realm), but it is today found throughout Europe (Austria, Britain, France, Spain, Italy, Hungary, Romania, Slovenia, Poland, Switzerland, and Moldova), in the Neotropical realm and in South Korea.
Adults of Metcalfa pruinosa can reach a length of 5.5–8 millimetres (7⁄32–5⁄16 in) and a width of 2–3 millimetres (5⁄64–1⁄8 in) at the widest point. They are initially whitish. The color of adults may vary from brown to gray, in connection with the presence of a bluish white epicuticular wax, covering especially the nymphs. The large and prominent compound eyes are yellow. The mouthparts are adapted for piercing and sucking. The trapezoidal forewings are held vertically, wrapping the body when the insect is at rest. The front wings have veined costal cell and several characteristic whitish spots. The hind tibiae usually have two lateral spines in addition to the other spines at the apex.

Possible
About 20% of wildlife watchers report a Citrus Flatid Planthopper sighting in Kharkiv on a given day, based on 34 verified sightings from GBIF citizen-science data. It is the 46th most-seen of the 289 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
August
In that month about 40% of wildlife watchers report a Citrus Flatid Planthopper in Kharkiv on a given day, against under 5% in June and November–April, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Citrus Flatid Planthopper sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 32 cities where we can rate Citrus Flatid Planthopper sightings, Kharkiv ranks 3rd at about 20%, level with the leaders once rounded. The best odds are in Sofia (Bulgaria, about 20%) and Kyiv (Ukraine, about 20%).
Same order: Hemiptera
The closest relatives of the Citrus Flatid Planthopper that you can see in Kharkiv (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are European Firebug (about 40%), Dock Bug (about 30%) and Green Shield Bug (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Citrus Flatid Planthopper is recorded against all the insects logged in Kharkiv (34 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.
