Can’t find anything online !! A few things I know: It comes out when it rains. It has huge wings and it has a stinger.
This is a Hellgrammite, the larval form of a Dobsonfly. When it matures into a winged adult, it is quite fierce looking, and the adults are sexually dimorphic. Male Dobsonflies have enormous sickle shaped mandibles, and despite the fierce appearance, they are harmless. Female Dobsonflies have much smaller, though more utilitarian mandibles that can be used to defend her against predators. We recently learned first hand what we have long suspected, that the bite of a female Dobsonfly might draw blood. You are misinformed about Dobsonflies or Hellgrammites possessing stingers.
