Zoomed this image out to see some more details. Ocelli are present. The bicolored antennae might be a useful diagnostic feature. This may be an example of a braconid that attacks sawflies (e.g. Ichneutinae), since sawflies are often found in flowers. As you know, you can never really exclude ichneumons from the equation without a good look at the wings, but I would go with your instincts on this one.
