The problem with eating virtual moths is they take a lot of bytes.
(get it? Hahaha! Oh, come on, that was a little funny..)
Virtual moths created in a lab have shown how evolution plays a role in how the fittest survive. Trained blue jays were shown images of moths created by computer imaging to have a certain genetic mix. The least commonly pecked moths had their virtual genes mixed and passed on to later generations, which the birds found more and more difficult to recognize.

It backs up the theory that predators learn to spot prey by common markings and know those are "food", and pass up those with rarer patterns.

Alan Bond and Alan Kamil, of the University of Nebraska, programmed the virtual moths sitting on tree bark backgrounds, which were then shown one at a time to the jays. Whenever a moth was pecked/eaten, the bird got a food pellet. If it didn't recognize the moth as anything it'd want to be seen eating, it could peck another area of the screen to move on to the next picture. The best camouflaged moths 'survived' and so the computer mixed up their patterns with each other as would happen if they mated. After 100 generations, and with a little bit of random mutation thrown in, the moths were about 30% harder to find.

I was just impressed with how smart those jays were; the hell with the moths. :)
