AboutA recent beneficiary of climate change, the Common Green Shield Bug was once restricted to Southern England. In recent years, however, it has been on the march, and is now common and widespread across much of England and Wales, and spreading further northwards. The Common Green Shield Bug feeds on a wide variety of plants, helping to make this one species which could turn up anywhere from garden to farm. Adults overwinter and emerge in spring, laying their eggs on the undersides of leaves. The rounded nymphs appear in June and new adults are present in early autumn.
How to identifyThere are two species of Green Shield Bug in the UK - one native (the Common Green Shield Bug) and one that arrived very recently from Europe (the Southern Green Shield Bug,
Nezara viridula). The Common Green Shield Bug is bright green with tiny black dots and dark wings, while the Southern Green Shield Bug is uniformly green in colour and has pale wing membranes.
