This sure looks like an Ichneumon to us, or some other parasitoid wasp, but we have not had any luck with a definitive identity. We wish there was more detail in your image. Ichneumons are parasitoid Wasps that are considered important biological control agents for caterpillars and other insects. According to BugGuide: “a great variety of hosts (mostly immature stages) is used, though most species attack only a few host types; some infest spiders and other non-insect arthropods.” The wing veination on your individual appears very similar to the drawing on Le Monde des Insectes.
