I took this photo last summer, and I am very curious about this bug...it was located on the outside of our house, near the front door...We have never seen anything like this in NJ, especially something this large (about 2 inches total length) and my parents have been living here at the same home for 20+ years now. Please let me know if anyone has any information about it!

Dobsonfly
Further to Troy's comment, there's a photo of the aquatic larva here. The text mentions "...can pinch hard with their big mandibles" but I don't know whether that refers to the larva only. The adults have huge mandibles but I wonder whether they're just for show; has anyone out there been pinched by an adult dobsonfly?

Dobsonfly
I have. It's the female that delivers the most painful bite. The male uses his long pincers primarily for show and to hold the female during mating. Best not to handle either gender. Darryl Searcy
