Their highly-miniaturized brains put our computers and aircraft avionics to shame. No one but God could make such a marvelous creature as a butterfly. God created butterflies and moths in many different shapes and color patterns. Perhaps this scares away predators. Moths are much more common than butterflies.
Butterflies are active during the day, moths at night.
As a result, they have different lifestyles and adaptations. Moths can be destructive. The largest butterfly in the world is the Giant Birdwing from the Solomon Islands. The smallest butterfly ever found was only half an inch long lengthwise. Rain forests are filled with many other fascinating and sometimes bizarre insects.
