About

These large shieldbugs are usually found on gorse or broom, but their larvae (known as nymphs) will also feed on other plants including dyer's greenweed. They occur just about anywhere that their host plants grow, including heathland and scrubby areas. The adults come in two colour forms. In spring they're mostly green, but the new generation that emerges in summer have purplish-red markings on their back. Their colouration can make them hard to spot on their host plants, but if you find one keep searching as there are likely to be more nearby.

How to identify

A fairly large shieldbug, with their typical shield-like shape. In spring, adults are green with a distinctive yellow margin on the sides of the pronotum (the section of body behind the head) and the abdomen. The antennae are red. In summer, parts of the back are reddish-brown.

Distribution

Widespread across the UK
