Will you please identify this bug for us? We are split between palo verde beetle and a pine sawyer. Let us know please! If it helps, it was found on the side of my house on July 9, 2008. It has been around 90 degrees here. I am in the Willamette Valley in Oregon. Thanks!!

Hi Alisa,
Your large Prionid is Ergates spiculatus which Hogue refers to as a Pine Sawyer, but BugGuide refers to this species as the Ponderosa Pine Borer to differentiate it from other species in the genus Monochamus commonly called Pine Sawyers.

Update: from Eric Eaton (07/11/2008)
P.S. I am so-o-o-o envious of the folks that found the Ergates! I lived in Oregon for what, 27 years, and never saw ONE! Well, ok, from 0-9 years probably doesn’t count….:-)
