Ergates spiculatus? Pine sawyer beetle and unknown ant - Trichocnemis spiculatus
Duncan, Vancouver Island, British Columbia, Canada
August 30, 2012
Size: 40 mm
I found the large beetle (40mm) upside down struggling on my sundeck in Douglas fir-forested area on Stoney Hill, near Maple Bay, BC. The ant was clinging to the beetle's abdomen even when I righted the beetle.

now it's Trichocnemis spiculatus... nice pic --thanks!
trimmed it a bit for the guide
