Imported Willow Leaf Beetle June 12 2012

This weeping willow in Harleysville has adult imported willow leaf beetles feeding on its leaves. They won’t cause much damage. But the population of beetles is rather high, and they will soon lay eggs. When the larvae of the next generation emerge from the eggs, they will feed on the leaves in a skeletonizing pattern, and there will be enough of them to defoliate the tree. The client is aware, and he will probably spray them.
