I came across some Arrowwood (Viburnum dentatum) in Prospect Park that been skeletonized by Viburnum Leaf Beetle (Pyrrhalta viburni). This invasive species that has been defoliating its way through numerous Viburnum species through the northeast.
The beetle — both the larval and adult stages are leaf-chewers — wasn’t found in NYC half a dozen years ago, but is seen here more commonly now. The plants, and there are a lot of Viburnums, can survive a few years of infestation, but ultimately succumb, unless measures are taken. Check out the link above for more details on tracking and fighting the infestation. Prospect Park is evidently resigned to losing its Arrowwoods.
