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.

With luck
About 10% of wildlife watchers report a Black-Shouldered Shieldbug sighting in Ecrins National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 70th most-seen of the 251 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Black-Shouldered Shieldbug is recorded against all the insects logged in Ecrins National Park (17 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.
