The Asian Longhorned Beetle is a destructive pest introduced from Asia, probably in wood packing material. Adults are about 1 to 1½ inches long, shiny black with white spots, 6 legs and long, jointed antennae with white bands. Asian Longhorned Beetles are most active in mid-summer to fall.
 

Damage From Asian Longhorned Beetles

Larva tunnel into trees, cutting off the flow of water and nutrients, usually killing the tree. Early signs of infestation include yellowing or dropping leaves, oozing sap, dime-size exit holes in trunk and limbs, shallow scars under the bark, sawdust where branches join other branches or at the base of the tree and dead limbs. Trees commonly attacked include birch, goldenrain tree, willow, horse chestnut, elm, katsura tree and especially maples.
