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.
