The striped ambrosia beetle is Holarctic in distribution and attack conifers in Abies, Picea, Pseudotsuga, Tsuga, Larix, and Pinus. Trypodendron lineatum belongs to ambrosia beetles and do not feed on wood, they feed on fungi. It galleries in the sapwood of thick stems of dead or dying trees. Females bore into the xylem and then larvae make lateral galleries where they feed, pupate, and later emerge. There is generally one generation per year.
