After leaves are no longer providing enough sustenance, larvae will move to the new, green-stem growth and chew the bark off of the young stems causing stem dieback. After that time, the adult beetles will emerge and they will also feed on the leaves, continuing to skeletonize them. Each female can deposit up to 500 eggs. In Wisconsin, an isolated infestation of VLB was discovered in Dane County in 2009, but was successfully eradicated.
