Also referred to as EAB, Emerald Ash Borers are wood boring insects with a one year lifecycle. They are metallic green with bronze on the head and under the elytra. About 13 mm long, indented along the elytra. Larvae are milky white with triangular segments. Adults lay eggs under the bark of ash trees. The larvae eat the tissues of the tree as they grow. Once they are mature the larvae exit the tree by boring a D shaped hole in the bark to escape. The D shaped exit hole is one way used to find an EAB infestation.
