Carpocoris purpureipennis is a species of shield bug of the family Pentatomidae, subfamily Pentatominae. This species can be found in most of Europe and in central Asia. They live in meadows, roadsides, edges of forests and gardens.
Carpocoris purpureipennis can reach a length of 11–13 millimetres (0.43–0.51 in). The pronotum is wide with a regular punctuation, almost straight and slightly pointed lateral margins with blunt tips. Also the lateral edges of the scutellum are nearly straight.
The body color varies from purple or reddish-brown to yellowish. The pronotum angles are black. Moreover pronotum usually shows short longitudinal black stripes, while the scutellum may have some contrasting black spots. Antennae are black and legs are orange.
This species is quite similar to, and can be easily confused with Carpocoris pudicus, C. fuscispinus, and C. mediterraneus. Both the adult bugs and their nymphs are polyphagous. Adults mainly feed on juices of Cirsium arvense and nectar of Leucanthemum vulgare.

Rare
Under 5% of wildlife watchers report a Black-Shouldered Shieldbug sighting in Cologne on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 200th most-seen of the 235 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July and August
In those months about 10% of wildlife watchers report a Black-Shouldered Shieldbug in Cologne on a given day, against under 5% in September to June, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Black-Shouldered Shieldbug sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
18th of 19
Of the 19 cities where we can rate Black-Shouldered Shieldbug sightings, Cologne ranks 18th at under 5%. The best odds are in Kharkiv (Ukraine, about 10%), Helsinki (Finland, about 10%) and Warsaw (Poland, about 10%).
GBIF citizen-science records
It is estimated from how often the Black-Shouldered Shieldbug is recorded against all the insects logged in Cologne (5 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.
