Tetropium abietis
Round-headed Fir Borer
Tetropium abietis is a longhorn beetle species in the family Cerambycidae, described by Fall in 1912. The common name "Round-headed Fir Borer" suggests an association with fir trees (genus Abies). It is a North American species with distribution records from Canada (British Columbia) and the United States. Like other members of the genus Tetropium, it is likely a wood-boring beetle whose larvae develop in coniferous trees.

Tetropium parvulum
Northern Spruce Borer
Tetropium parvulum, the northern spruce borer, is a small cerambycid beetle specialized on spruce hosts. It was elevated from synonymy with T. cinnamopterum based on distinct morphological differences in larvae and adults, and exhibits strict host specificity to Picea compared to the conifer generalist T. cinnamopterum. The species has a one-year life cycle and is an economically important borer of white and Engelmann spruce logs in western Canada.
