Great Grig

An intruder in my tent
This one was in my tent at Wilcox Creek Campsite in the Canadian Rockies, in mid-August. It moved quite slowly and did not attempt to fly. The nearest thing I have found on the web is a rove beetle, but nothing matches completely. Can you help…..

We found your Great Grig, Cyphoderris monstrosa, on BugGuide. Elsewhere on BugGuide, Eric Eaton refers to it as a Humpbacked Grig and states: “They are most closely related to katydids and crickets, but are in a family all to themselves (Prophalangopsidae). The genus is Cyphoderris.” Your letter was a good reason to create a brand new page for our site.
