- As an adult, Halyomorpha halys is a 12-17 mm long mottled brown coloured stink bug, shaped like a shield
- Very wide host range and affects many plants, including tree nuts such as hazelnut, pecan and potentially walnuts
- Originally from eastern Asia, but recently introduced to North America and Europe where it is having a significant impact on agriculture and as a nuisance pest
- Saliva causes significant damage to plant tissues
- Eggs are cream to yellow-orange and approximately 1.6 mm long and laid in clusters on the underside of leaves
- Five nymph stages that range from less than 3 mm to 12 mm long. The nymphs are orange and black when they first hatch but quickly develop a similar colouration to the adults
- The adults and larvae can be confused with a number of other brown coloured stinkbugs that are present in Australia
- Hitchhikes in container shipments of a range of commodities, including plant material. Adults are capable of flight allowing localised spread of the pest
