Not really dead at all - these clean looking moths make it simple to get underneath shots by remaining completely still for up to a minute if upturned. About 40mm long, mostly white with many dark spots and a striking flash of vermilion around the thorax. Attracted to powerful night lights above a car at a national park.
One of the few species I have found whose larvae can feed on Tradescantia which has become a noxious weed around here. Go mothy !!
