Brown Spruce Longhorn Beetle

Native to Europe, this invasive forest pest infests and can eventually kill spruce trees including red, white, black, and Norway. It has been found in populations around Calhoun, New Brunswick, but was first identified in Halifax, Nova Scotia in 1999. Likely introduced through infested wood packaging, these beetles lay eggs under the bark scales and in crevices of spruce trees. These eggs become larvae that bore holes into the live bark, and spruce trees to respond to this attack by producing a large amount of tree resin which flows out of these holes and down the tree. Large amounts of resin coming from holes in spruce bark can indicate BSLB infestation; the more resin, the more severe the attack.
