Emerald Ash Borer

The adult EAB beetle lays eggs on the bark of ash trees.  The eggs hatch, and the EAB larvae feed under the bark of the tree.  These larvae create galleries, and eventually kill the tree.  The tree may look healthy, but it is being strangled.  EAB is so invasive and so aggressive that all native ash may die within two to four years after becoming infested.



Gypsy Moth

The Gypsy moth goes through four stages of development, egg, larvae (caterpillar), pupa (cocoon), and the moth.  The caterpillar stage is devastating.  Groups of caterpillars feed during the night, chewing small holes in leaves, and progress to feeding from the outer edge of the leaf toward the center.  When populations of caterpillars are dense, they may feed continually day and night until the tree is stripped of leaves.
