Coreus marginatus is a herbivorous species of true bug in the family Coreidae. It is commonly known as the dock bug as it feeds on the leaves and seeds of docks and sorrels. It is a medium-sized speckled brown insect, between 13 and 15 mm long as an adult, with a broad abdomen. It occurs throughout Europe, Asia and northern Africa. It is often found in dense vegetation, such as hedgerows and wasteland.
This species was among the first Hemiptera formally described in the scientific literature by the Swedish biologist Carl Linnaeus in 1758, under the name Cimex marginatus. It was transferred to the genus Coreus by the Danish zoologist Johan Fabricius in 1794. It has numerous synonyms and was historically placed in the genus Syromastus.
The specific epithet marginatus refers to the prominent margins of the abdomen. The head, pronotum and abdomen of an adult dock bug are speckled reddish brown. The antennae are composed of four segments, red-orange in colour except for the final fourth segment which is black. Between the antennae are two small projections, known as antenniferous tubercles, which can be used to distinguish this species from other superficially... Wikipedia →

Possible
About 20% of wildlife watchers report a Dock Bug sighting in Budapest on a given day, based on 37 verified sightings from GBIF citizen-science data. It is the 48th most-seen of the 404 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.
April–June and August
In those months about 20% of wildlife watchers report a Dock Bug in Budapest on a given day, against under 5% in September to March, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Dock Bug sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
11th of 40
Of the 40 cities where we can rate Dock Bug sightings, Budapest ranks 11th at about 20%. The best odds are in Kharkiv (Ukraine, about 30%), Liverpool (United Kingdom, about 30%) and Birmingham (United Kingdom, about 30%).

GBIF citizen-science records
It is estimated from how often the Dock Bug is recorded against all the insects logged in Budapest (37 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.
