Red neck longhorn beetle
Red neck longhorn beetle (Aromia bungii) is an insect pest of hardwood trees. It is a native of China and Taiwan and was first detected in Washington in 2008.
Aromia colonize trees that are slightly stressed, where larvae develop for two to three years in the subcortical area of the trunk. Adult beetles appear in June and oviposit for two or more weeks following emergence. Aromia seem to prefer young trees and are capable of weakening and killing small trees. It could enter the country through solid wood packing or Prunus nursery plants.
