Habitats and host plants
The pest has been found in a wide range of habitats, including: suburban areas, gardens, hedgerows, forests and woodlands.
Apart from fruit crops, other hosts include: wild blackberry, wild cherry, dogwood, elderberry, hawthorn, honeysuckle, mahonia, mountain ash (rowan), mulberry, nightshade, wild raspberry, rose and snowberry. Early and late sugar sources include: holly, insect honeydew and ivy.
Wild blackberry is an important host in the UK.
