Listen to the murmer of the cottonwood...

Mowing the grass this morning I noticed that I appear to have a beetle infestation at the base of my willow tree. A little research indicates that the critter in question seems to be the cottonwood borer, which is a beautiful bug, but is gonna kill my willow tree, so I'm off to Home Depot to get some pesticide, unless someone can get me a workable organic solution in the next half hour.

I'll try to take some photos before I kill the fuckers--they really are some lovely and interesting bugs.

UPDATE: Photographs taken, and will be uploaded eventually. Home Depot suggested a product by Bayer for extermination.

UPDATE THE SECOND: Here's a picture--fairly close to actual size:
