Lygus hesperus
Western Tarnished Plant Bug
Lygus hesperus is a significant agricultural pest in western North America, causing extensive damage to cotton, strawberries, alfalfa seed, and other crops. In California alone, annual losses exceed $30 million in cotton and $40 million in strawberries. Adults overwinter in reproductive diapause triggered by short day lengths, resuming activity when conditions improve. The species has been the subject of extensive research on sampling methods, biological control, and insecticide resistance.

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.
