Butterfly Physics and Stealth

On today’s Creation Moments Minute, see why fast birds have such a hard time having slow-moving butterflies for lunch.


How do slow-moving butterflies avoid being lunch for fast-flying birds? The muscles that control the tasty butterfly’s wing are relatively stronger in terms of lifting power than a bird’s muscle. In addition, tasty butterflies have about 50 percent more flight muscle than the poisonous butterflies that birds avoid. Since butterflies weigh so much less than birds, they can change direction more rapidly. So even though a bird can fly much faster than a butterfly, by flying in a tight, darting, erratic pattern, a skillful butterfly can easily escape.

Not only is the butterfly wonderfully designed, it’s designed in view of the birds that might eat it. Notice how God carefully countered the bird’s advantage of speed by giving the butterfly stronger muscles and a more maneuverable body. Darwinism can only pretend to explain that!
