• Tetropium cinnamopterum

  Eastern Larch Borer

  Tetropium cinnamopterum is a native North American cerambycid beetle in the tribe Tetropiini. Adults are distinguished from the closely related T. parvulum by eye shape, scutellar structure, external genitalia, and pronotal puncture number; larvae are distinguished by urogomphi morphology. The species has been recorded from various conifer hosts, with larvae developing in conifer wood. It is transcontinental in Canada and occurs sympatrically with invasive T. fuscum in Atlantic Canada, where cross-attraction to the aggregation pheromone fuscumol may occur. Both sexes respond to (S)-fuscumol synergized by host monoterpenes and ethanol.
