Based on other photos on you site I believe this is a photo of a Dobson fly. Am I correct? This Insect was photographed near the Hiawasse river in Murphy NC.
Yes, this is a male Dobsonfly. Despite those formidible looking jaws, he is harmless. Now that summer is arriving, we expect to get many queries targeting the Dobsonfly. Fishermen use the equally fearsome appearing larvae, known as Hellgrammites, as bait. Your photo is marvelous, and we have decided to feature it near the top of our webpage for the entire month.
