Issus coleoptratus is a species of planthopper belonging to the family Issidae, named by the Danish zoologist Johan Christian Fabricius in 1781. This common species can be found in the western Palearctic realm, in the Near East, and in North Africa. These insects live on shrubbery and on foliage of various woody plants and common deciduous trees and in mixed forests (forest edges and parks).
Issus coleoptratus can reach a length of 5.5–7.0 millimetres (0.22–0.28 in). The coloration of these planthoppers can vary from light brown and olive to nearly black. The head, including the eyes, is narrower than the pronotum. The forehead is usually dark brown to black in the upper third, with lighter spots. In the lower area it is greenish, yellowish or brownish. The leathery wings usually show a huge number of dark brown cross-veins with a dark brown discal spot and some evidence of banding. The forewing veins of males and females differs (sexual dimorphism), as they are effaced distally in the female, while in males they are throughout prominent. This species is very similar to the much rarer Issus muscaeformis.

Possible
About 20% of wildlife watchers report an Issus coleoptratus sighting in Berlin on a given day, based on 592 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 1065 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
February–March, June–July and October–December
In those months about 30% of wildlife watchers report an Issus coleoptratus in Berlin on a given day, against about 20% in January, April–May and August–September, the lowest months.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Issus coleoptratus sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 16 cities where we can rate Issus coleoptratus sightings, Berlin has the highest daily chance: about 20%. Next come Hamburg (Germany, about 10%) and Vienna (Austria, about 10%).
Same order: Hemiptera
The closest relatives of the Issus coleoptratus that you can see in Berlin (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are European Firebug (about 40%), Brown Marmorated Stink 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 Issus coleoptratus is recorded against all the insects logged in Berlin (592 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.
