I think the Eight-spotted Forester is not so much a "butterfly-imitating" moth than it is a wasp mimic, although there are other day-flying moths that look more convincingly like a stinging hymenoptera. Being a defensless, non stinging, non biting nectar sipper out in the light of day, it would behoove such a creature to look like something more dangerous to a potential predator. I would think that looking like a butterfly would be just asking for trouble.
I wonder if the red legs and yellow "flanks" are meant to resemble the pollen that often collects in the legs of hymenoptera? Or if it's a warning of unpalatability?
These moths are in the noctuidae family (Owlet), but if you look at the antennae, they resemble those of a skipper - getting thicker towards the end. Pretty special creatures - wish I had them in my yard! (I do get two of their cousins, the Beautiful and Pearly Wood-nymphs(Eudryas grata and unio), at my lights, and the occasional Grapevine Epimenis(Psychomorpha epimenis) at Chatfield Hollow "around the corner")
