Hylurgops palliatus breeds in conifers of the family Pinaceae including species of fir, true cedar, larch, spruce, and pine. It appears to occur more commonly in fir and spruce and is less common in true cedar, larch, and pine.
Hylurgops (Hylurgus) palliatus is considered primarily a secondary invader in Europe. However, it allegedly is a vector of Leptographium and Graphium (blue-stain) fungi.
The Exotic bark beetle is not known to occur in Indiana.
