Extract

An instance of the California pine engraver (Ips plastographus Leconte) hibernating in short tunnels in the sapwood of host trees was observed during an examination of a windfelled lodgepole pine forest at the 6,100-foot elevation on Parsnip Mountain, Kootenai National Forest (Lincoln County), Montana on September 27, 1950. The above examination disclosed that (1) the new adult beetles were overwintering in windfelled trees previously unattacked, and (2) the adults were seeking shelter in short tunnels that penetrated the bole sapwood of these trees.
