What does the pest look like?
Adult Sycamore lace bugs are approximately 3mm long and white in colour. They have a lace-like pattern on their wings, head and thorax. Immature nymphs are smaller than adults and have light and dark bands or patches on their body.
Impacts and damage
The Sycamore lace bug affects amenity trees such as sycamore or plane trees, which are planted as ornamental trees in gardens and along street verges.
Sycamore lace bugs feed on the undersides of the leaves, initially causing a white stippling that can progress to bronzed foliage and premature senescence of leaves. In cases of severe infestations, especially if the trees are water-stressed, they may be defoliated.
Sycamore lace bug is not a significant pest for agriculture production and is present in other parts of Australia.
A variety of insecticides and application methods for Sycamore lace bug are available on the Australian Pesticides and Veterinary Medicines Authority website.
