Main: (Noctuidae / Heliothinae)
73.076 [B&F: 2400] Scarce Bordered Straw or Old World Bollworm (Helicoverpa armigera) (Hübner, [1808])

 

Notes: A moderately frequent immigrant from southern Europe, north to Shetland. In Hampshire and on the Isle of Wight moderately common and widely distributed throughout in some years. Wingspan 30-40 mm. The main confusion species are Bordered Straw Heliothis peltigera, which has forewing with a distinctive marginal dot above the tornus, and with reniform stigma usually joined to the costa by a dark triangular wedge, and Eastern Bordered Straw Heliothis nubigera, which has forewing more mottled, subterminal band more indented, and pronounced marginal dots (MBGBI Vol 10). Larva polyphagous, most likely to be found in Britain on imported fruit and cut flowers, but a pest on crops such as Tomato and Maize, causing sufficient damage to be a serious pest in some areas.
