identification as A. glabripennis. This pest was collected on
maple and horse chestnut trees by the New York City Parks and
Recreation Department at Green Point in northern Brooklyn
County. It was initially identified by E. Richard Hoebeke of
Cornell University. The Longhorned beetle is a pest found in
China, Japan and Korea. This was the first detection of this
pest in the United States. The early stages of larvae of this
beetle feed between the xylem and the phloem, and the later
stages feed only on the xylem, inhibiting the tree's vascular
system. It is most destructive when larvae cross perpendicular
to the flow, thereby cutting off many vascular paths. Larvae can
cut off the flow from vasular tissue and essentially gir
