What does the Emerald Ash Borer (EAB) look like?
The larva of the beetle is the destructive stage of the life cycle, disrupting the movement of nutrients and water uptake in the tree. A full-grown larva averages 1-1/2" in length and has a series of bell-shaped body segments.
This beetle attacks only true ash (Fraxinus sp.) including green ash (F. pennsylvanica), white ash (F. Americana), black ash (F. nigra) and blue ash (F. quadrangulata). Mountain ash (Sorbus sp.) is not a true ash and not susceptible to the borer.
