The abdomen looks twisted but it is still colored, so presumably recently deceased. There appear to be only 2 'tails' (caudal filaments, sort of rear-facing antennae), when I think mayflies usually (always?) have 3, so that might say stonefly, which do have 2 (Plecoptera). On the other hand the caudal filaments are fragile and often break off, and there looks like a break in one in the picture, so maybe there once were 3? You'd expect a single ovipositor in an ichneumon and more of a 'waist', but I suppose if it was dead the sheath on the ovipositor might have become displaced, so you could be right on the ID. Exotic wing venation looks more typical of a 'lower' insect group than a hymenopteran, though, and mayflies are next but one to the bottom of the winged insect tree. You need someone authoritative on this one (= not me) -- perhaps Dave McC in Cape Breton U could offer a better judgment if he's reading this.
