Anyway - we all know about the various ways animals hide themselves in nature - their natural stripes forming patterns that help them blend in with their environment, etc. And, we have occasionally heard of creatures mimicking the threatening behavior of creatures known to prey on THEIR predators. Honestly- I don't know how that happens in nature - it's one of those things that seems excessively unlikely to be evolved - it just SEEMS so deliberate! And then you come across something like this - which, if its not a hoax - is just beyond incredible...
OK - see that? THAT is a butterfly, looking for all the world, like a lurking kitten - of the bird catching variety. Um...!
More brilliant minds than mine can probably explain it (or declare it a hoax) but I am stunningly amazed by this image.
Scientific and other explanations welcome!

Some have argued that though we anthropomorphize them as eyes, they actually work by other means. Whatever the mechanism, they certainly seem to distract from outline recognition and other food-finding strategies, so this easy-to-develop pattern may leave other prey species easier to recognize. Note that your example butterfly sports a second pair of ocelli, which would stand out more against other backgrounds.

My favourite "cheats" are hoverflies: they pretend to be dangerous bees or wasps while actually they are absolutely harmless vegetarians without a sting:
