Flathead Poplar Borer / Dicerca tenebrica

Lol, I happened to notice this insect on a friend's back when a few of us spent the day botanizing the Small Whaleback on July 10th. He must have imagined something this huge after my deliberately exaggerated exclamations (knowing that he couldn't see it himself, ha). A good job, though, that no one did that to me, as I know I would never have stood still! I think I have identified it correctly, but please let me know if I'm wrong - thanks!

This species is 17-19 mm (0.67 - 0.75 inches) long, is found in Montaine, hardwood and boreal forests from May to July, feeds on Aspen and Balsam Poplar, and is a widespread species found thoughout Canada.
