Green shield bugs live on plants, where they eat plant sap and unripe seeds. They are found in hedgerows, grasslands and woodland edges. It is also common on horticultural crops and in nearby roadside vegetation. Female green shield bugs lay several groups of 20-30 barrel-shaped eggs on plant leaves, up to 200 eggs per female. These hatch into wingless nymphs that crawl between plants to feed. The life cycle from egg to adult takes about six weeks and there can be two or more generations per year in the summer season. They hibernate for the winter as adults. Unlike many insects, shield bugs often show parental care, guarding their young from predators.
