Moth or ??
August 19, 2009
I found this moth like buy in front of my garage door under where the hallogen light is. Usually I find many lunar moths there but found this today. Approx 3 inches long, narrow moth like bug. Pinchers on the front and antenae above the pinchers.
Do you have any idea what it is? I have searched some moth web sites etc,,,,but cannot find anything similar.

Male Dobsonfly

Male Dobsonfly

Hi Deb,
Now that you know that this is a male Dobsonfly, you should be able to locate a wealth of online information. Female Dobsonflies have much smaller mandibles.   Since we just finished posting some marvelous images of a female Dobsonfly from Peru, we feel compelled to post your photo as well.

      We understand they give off a foul odor as well. Though frightening, male Dobsonflies are perfectly harmless, though one might accidentally fly into a person’s eye, in which case those sabre mandibles might do some serious damage. Larval Hellgrammites and adult female Dobsonflies both have much more practical mandibles, for defense in her case and capturing prey in the larva’s case, and an encounter with a thin skinned person might result in the loss of some blood.
