Confidence: It's likely to be this, but I can't be certain.
Notes: I should be grateful to have some idea of ID to the extent that the images allow. Parasitica I presume, from the nature of the antennae. Because the wings overlap the end of the abdomen I can’t see if there is an ovipositor. Do all female, parasitic wasps/ichneumons have an ovipositor or can some, lacking one, simply drop eggs near the host?
