Mystery bug…ID found?

I’ve been looking for answers and appreciate the comments received. So, I wanted to see what y’all thought about this potential ID – a type of stonefly (photos look similar to a salmon fly and a giant stonefly).

Here is my iPhone image of the mystery bug.

Either way – it is the first time I’ve seen such a critter at the farm, we DO live near the New River (not sure about its pollution status but if this guy came from that body of water he says it is clean), and from what I have read about stoneflies, they are interesting bugs highly sought after by fishermen (particularly fly fishermen). Apparently, trout love them.

Here is a link to Wikipedia for information about stoneflies.

A quick run down of info from NCSU’s general entomology site :

“Stoneflies – The name Plecoptera, derived from the Greek “pleco” meaning folded and “ptera” meaning wing, refers to the pleated hind wings which fold under the front wings when the insect is at rest. Stoneflies are generally regarded as the earliest group of Neoptera.  They probably represent an evolutionary “dead end” that diverged well over 300 million years ago.  Immature stoneflies are aquatic nymphs (naiads).  They usually live beneath stones in fast-moving, well-aerated water.  Oxygen diffuses through the exoskeleton or into tracheal gills located on the thorax, behind the head, or around the anus. Most species feed on algae and other submerged vegetation, but two families (Perlidae and Chloroperlidae) are predators of mayfly nymphs (Ephemeroptera) and other small aquatic insects.  Adult stoneflies are generally found on the banks of streams and rivers from which they have emerged.  They are not active fliers and usually remain near the ground where they feed on algae or lichens.  In many species, the adults are short-lived and do not have functional mouthparts.  Stoneflies are most abundant in cool, temperate climates. Stoneflies require clean, well-oxygenated water to survive.  They are extremely sensitive to water pollution and are used by ecologists as indicators of water purity.  Stoneflies are also an important source of food for game fish (e.g., trout and bass) in cold mountain streams. “

What do y’all think about this ID?
