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.

Rare
Under 5% of wildlife watchers report a Citrus Flatid Planthopper sighting in Prague on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 470th 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 20%, if each day is a fresh chance.
July to September
In those months about 10% of wildlife watchers report a Citrus Flatid Planthopper in Prague on a given day, against under 5% in October to June, 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.
30th of 32
Of the 32 cities where we can rate Citrus Flatid Planthopper sightings, Prague ranks 30th at under 5%. The best odds are in Sofia (Bulgaria, about 20%), Kyiv (Ukraine, about 20%) and Kharkiv (Ukraine, about 20%).
Same order: Hemiptera
The closest relatives of the Citrus Flatid Planthopper that you can see in Prague (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are European Firebug (about 40%), Brown Marmorated Stink Bug (about 20%) and Green Shield Bug (about 20%), 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 Prague (9 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.
