What: Asian long-horned beetle, one of the most destructive
plant pests, was found in Chicago.
When: Start from July 9, 1998
Who: Asian long-horned beetle is 1 1/4" long, coal black with irregular white spots on its back. It has 2" long black antennae with white rings. The females chew oval, darkened notches in the bark of trees, into which they deposit their eggs. After the eggs hatch, the larvae bore into the tree, feeding on the wood. The larvae may feed on the heartwood of the tree all winter. The beetle can attack and eventually kill healthy mature hardwoods due to heavy larval feeding in the heartwood, which inhibits the tree's vascular system. It prefers maples and horse chestnut.
