Male Dobsonfly in threat Position in Costa Rica

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.
