It prefers to colonize thin-bark parts of the trees and especially branches or whorls. He's usually as an insignificant colonizers weakened branches, twigs and brushwood radicals and weaker stems ( stem wood active). The feeding picture is a square-shaped mother duct from which closely spaced, winding, two to four centimeters long larval ducts emanate.
