Striped Shieldbug Graphosoma italicum Family: Pentatomidae A truly unmistakable species. G. italicum was previously considered a subpsecies of G. lineatum, but has recently been elevated to species status. The true lineatum has entirely red legs and is not found outside parts of the Mediterranean. Adults and nymphs feed on various umbellifers and there is one generation a year. Although well established in the Channel Islands, it was not recorded as breeding on the British mainland until 2020, when two populations were found at sites in the London area. These were associated with Common Hogweed and Hemlock. Adult: All year Length 8-11 mm
