Eggs are deposited between bark crevices, flakes, or cracks and hatch about two weeks later.
To exit the tree, adults chew holes from their chamber through the bark, which leaves a characteristic D-shaped exit hole. Immature larvae can over winter in their larval gallery, but can require an additional summer of feeding before overwintering again and emerging as adults the following spring.
According to the NJ Department of Agriculture, ALL ash trees in NJ should be considered at high risk for EAB: Even if Emerald Ash Borer has not yet been detected, all ash trees are considered to be at high risk of EAB infestation within the next few years.
