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.

With luck
About 10% of wildlife watchers report an Issus coleoptratus sighting in Bavarian Forest National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 523rd most-seen of the 1115 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May to July
In those months about 10% of wildlife watchers report an Issus coleoptratus in Bavarian Forest National Park on a given day, against under 5% in August to April, 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.
Among the best
Of the 2 parks where we can rate Issus coleoptratus sightings, Bavarian Forest National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Cévennes National Park (France, about 10%).
Same order: Hemiptera
The closest relatives of the Issus coleoptratus that you can see in Bavarian Forest National Park (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are Forest Bug (about 20%), European Firebug (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 Issus coleoptratus is recorded against all the insects logged in Bavarian Forest National Park (10 verified sightings from 2019 to 2026), 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.
