Corizus hyoscyami (a rhopalid bug) may also be included in identification literature listed under the following higher taxa:

NBNNBN (data.nbn.org.uk) has a distribution map for Corizus hyoscyami (a rhopalid bug)
BioInfoBioInfo (www.bioinfo.org.uk) has 3 host/parasite/foodplant and/or other relationships for Corizus hyoscyami (a rhopalid bug)

This striking species was restricted to western and south-western coasts, from Sussex to Lancashire in the last century. Since 2000 it has greatly increased its range and is now widespread in England and Wales, being found both near the coast and inland as far north as Yorkshire.

There are a number of superficially similar black and red bugs on the continent which may arrive here. Confirmatory characters include the numerous close parallel veins on the (dark) membrane of the wing, the upturned apex of the scutellum and the protruding stink glands between the second and third legs which are visible from above.
