Life Cycle of the

Emerald Ash Borer


   A.   The larvae live under the bark of the tree, feeding on the vascular cambium.

  B.  The larval feeding leaves 'galleries' under the bark that interrupt nutrient flow to the canopy and eventually kill the tree.

  C.  The adult is a small, metallic green beetle only 10-15 mm in length. The adult typically emerge around June, leaving D-shaped exit holes in the bark.  The adults feed briefly in the tree canopy before reproducing and laying eggs in the twigs and branches.

  D.  The larvae will start feeding in the branches at the top of the tree and work their way down.  The first symptom in an infested tree is dieback and in the tree canopy.
