After the last entry about camouflage, some of these species seem to be quite the opposite - rather blatant. Bright colouration can, of course, still be protective: some species are toxic and don't mind being easy to see.
I rarely see dead Ichneumonids: they seem to be largely free from predators. I rather liked this rosy one (although I tend to be seduced by any Ichneumonid, really).

Orange Tips are protected by their internal store of mustard oil, which they obtain from the host plant as a larva, and the orange wing-tips of the males are a warning signal to any passing birds.
