Anisota stigma is extinct in CT and protected in Massachusetts. In Massachusetts, it only occurs in the state's most extensive barrens. I don't think it has ever been recorded from VT, NH, ME, with VT being the least likely of the six states. No suitable habitat. (David Wagner - personal communication)
