I kept checking the arrowwoods damaged by VLB larvae and finally found two adults today. The poor shrubs have to get ready for the oncoming attack. We'll try to take some measures, but fear the worst from this invasive.
I found signs of their damage in two other nature centers in the next county.
We first noticed the larvae causing damage to some of the arrowwoods at Briar Bush Nature Center last May. They were out of sight, pupating underground for a couple of weeks.
