Stumphumping Horntail

Stumphumper Horntail Wasp

On a sunny November sunday, I photographed this wasp at Oaks Bottom Wildlife Refuge in Portland, Oregon. Not entirely sure, but I believe this is a species of horntail. Here in Oregon, lumberjacks refer to these wasps as stumphumpers, or even stump****ers. Great name for a wasp whose females drill into logs with a drill attached to their behinds.
