Ynghylch

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.
