Where do adult Emerald Ash Borers typically lay their eggs?

Adult Emerald Ash Borers typically lay their eggs between the layers of the bark of ash trees. This location is ideal for several reasons. Firstly, the thin layer of bark provides a protective environment for the eggs, shielding them from predators and environmental conditions. Secondly, once the eggs hatch, the larvae have immediate access to the inner bark and cambium layer, which they need to feed on in order to grow and develop. This feeding behavior disrupts the tree's vascular system, leading to the decline and eventual death of the tree. The other choices, while plausible locations for different insects, do not provide the same level of protection or access to resources essential for the Emerald Ash Borer's lifecycle.
