Invasive non-native on Viburnum dentatum, arrowwood - Pyrrhalta viburni
Briar Bush Nature Center, Montgomery County, Pennsylvania, USA
June 27, 2011
Size: 5 mm
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.

Hope you get those under control. I reccomend natural pesticide or ladybugs.

Treatments
At the local nature center, we have been pruning and destroying infested twigs and branches during the winter. We haven't had much success because they are easy to miss.
Curiously, the viburnums in my condominium are doing a lot better. Maybe some varieties are naturally more resistant than others. I started collecting seeds. We may need them. Wish us luck.
