Percevejo (Adulto) / Squashbug (Adult).
A large and distinctive dark grey squashbug with cream markings on the connexivum. Early instar larvae have very spiny antennae and a green abdomen. Later instars are superficially similar to the much commoner Coreus marginatus but the abdominal tergites are more pointed.
A local species which is mostly confined to coastal areas between Kent and mid-Wales, favouring dry open habitats such as sand dunes and soft cliffs. The larval foodplant is scentless mayweed and other Compositae.
Adult: All year
Length 11-12 mm
