Dear Jessica,
This is a female Dobsonfly and we would caution you and your aunt to stay clear of her mandibles.  Adult Dobsonflies do not eat, but the mandibles of the female are used to defend herself from predators, and she may deliver a painful nip if carelessly handled.  There is nothing to fear from the nip, as the Dobsonfly has neither venom nor poison.  The male Dobsonfly has much more spectacular mandibles, but they are not capable of inflicting a bite on a human.
