Adult beetles are somewhat elongate, cylindrical, and range in length from 2.0 to 3.4 mm.
Mixed bands or spots are produced by dense patches of bright and dark-colored scales.
Larvae are legless grubs with a light-brown head and a white, slightly curved body.
Host plants:
Green and White Ash; autumn purple ash is a favored host
Territory: It is found in North America
Damage caused by Eastern Ash Bark Beetle:
These beetles are known for infesting and destroying many big Ash trees (both green and white) in a region. Adult beetles cut egg galleries beneath the bark, and larvae tunnel and girdle; they can occasionally destroy branches. This beetle cannot generally live on younger trees because they are tougher and generate more sap than older trees.
Life history and Habits:
Overwintering adults fly to vulnerable trees to burrow under the bark and lay eggs in the spring. Pupae develop in tiny cells at the ends of their tubes. New adults burrow to the surface of the bark. Each year, one to two generations are born. Overwintering adults live in short feeding tunnels in the bark of living or freshly killed trees.
