Hi Scared,
Don’t be afraid. Male Dobsonflies are quite harmless despite the sabre like mandibles and threat posture. The female Dobsonfly has more modest mandibles, but hers can produce a nipping bite. The male uses his trophey mandibles during the mating process, or so we have read, but we have never been lucky enough to have a photo of a mating pair to proove this statement.
