According to the Indiana Department of Natural Resources (DNR), a new, exotic beetle feeding on ash (Fraxinus sp.) trees was discovered in southeastern Michigan and identified in July 2002 as Agrilus planipennis Fairmaire (Coleoptera: Buprestidae). Larvae feed in the phloem and outer sapwood, producing galleries that eventually girdle and kill branches and entire trees. On April 21, 2004, Emerald Ash Borer (EAB) was confirmed in Indiana. The Indiana DNR has a March 16, 2007 map with of quarantined townships and counties .

Ohio State University provides a comprehensive fact sheet on identifying ash trees

Purdue Univeristy's Entomology Extension provides a wealth of information on the dangers of EAB on its website, http://www.entm.purdue.edu/EAB.

The website also provides information on identifying ash trees, in addition to the symptoms of EAB disease and help with differentiating this disease from others that affect ash trees.

On its own, EAB moves slowly through the landscape; natural spread of the insect is about half of a mile or less annually. However, humans can greatly accelerate EAB's spread by moving infested ash wood, especially firewood and logs to un-infested areas. EAB movement into parts of Michigan outside of the Detroit area, Ohio, and Indiana has been the direct result of firewood and log movement.
