Pale Snaketail (Ophiogomphus severus): This dragonfly is primarily a stream and river species, but can also be found in large numbers in fields not far from water. They can be found from parts of northern New Mexico north and westward through the Rockies to Oregon, Washington, Idaho, Montana, and into western Canada.
