Emerald Ash Borer Behavior and Diet Emerald ash borers are known as wood boring insects. However, what sets the emerald ash borer apart from other wood boring insects is their tendency to attack native and newly introduced ash trees. The species typically chooses ash trees that have already begun to deteriorate and will begin to burrow just under the bark of the tree throughout the winter and then chew their way out in early June. Emerald Ash Borer Reproduction The emerald ash borer is known to have a one or two-year life cycle. Adult ash borers begin to emerge in mid-spring and peak in early summer. It is a couple of weeks after emerging that the female emerald ash borers will begin to lay their eggs into the bark of the selected ash tree. Once born, the new larvae will begin to feed for several weeks under the tree bark. Emerald Ash Borer's in Iowa Along with other Midwestern states, Iowa has fallen victim to emerald ash borer infestations. Though these wood boring insects are not as common in urban or residential areas, an infestation can still occur. Signs of an Emerald Ash Borer Infestation The way to identify an ash tree that has been infested with emerald ash borers is to observe wilting and dying of the upper crown of the tree. Upon closer examination, the ash tree may reveal bumps and ridges on the branches and limbs, as well as possible 'D' shaped holes in the bark where the emerald ash borer adults emerge. When the bark is removed as a result of the copious amounts of ridges that appear, you'll see irregular and winding tunnels known as galleries. These tunnels are made from the larva excavating the plant material between the wood and bark. These wood-boring insects tend to attack the crown of the tree first and continue to tunnel through the tree, ultimately killing it.
