Dear Bug Master,
This is a Root Borer in the genus Prionus, and we strongly suspect it is a California Root Borer, Prionus californicus, which is pictured on BugGuide. Despite its name, the California Root Borer’s range includes much of western North America. We would not rule out that it might be Prionus heroicus, which is also reported from Utah on BugGuide. Either way, those impressive antennae indicate this is a male Root Borer. Root Borers have powerful mandibles, so they should be handled with caution, but they are not considered dangerous. Many species are attracted to lights.
