Those antennae lead us to believe that this is some species of Ichneumon, a family of parasitoid Wasps whose larvae feed on the internal organs of host-specific Arachnids and immature insects including Caterpillars, Beetle grubs and larvae of wood boring Wasps. This is an enormous family with according to BugGuide: “~5,000 described spp. in almost 500 genera in the Nearctic Region, possibly 3,000 more undescribed.” We doubt it is your species because it is not reported as far north or west, but your individual does resemble Limonethe maurator which is pictured on BugGuide.
