Cause of Death to Trees
The adult emerald ash borer emerges in May-July and the female lays numerous eggs in bark crevices and between layers of bark. The eggs hatch in 7-10 days and larvae bore into the tree where they chew the inner bark and phloem creating serpentine galleries as they feed. This cuts off the flow of water and nutrients in the tree, causing dieback and eventual death of the tree.
