Excerpt from The Fir Engraver Beetle: A Serious Enemy of White Fir and Red Fir Attacks are made along the main trunk, usually in roughened bark surrounding the bases of branches. When a suitable spot has been selected for an entrance hole, the female rotates about it and cuts bits of bark away. Within from 36 to 48 hours the hole is ex tended at an upward slant to the cambium layer. The surfaces of the sapwood and inner bark are then deeply grooved to form a nuptial chamber large enough to accommodate two beetles.
