Scientists have relocated monarchs to other locations within the Unites States and have found that they migrate according to the pattern of the resident monarch population to which they were transferred. This shows that they truly navigate and that there is intelligence designed into their navigation system. For example, the monarch’s brain (the size of a pin head) interprets 72,000 electrical pulses from the eyes to translate the picture the butterfly is seeing. It also computes the angle of polarized light that it sees to determine the sun’s orientation and it’s position on earth. Inside the monarch’s brain and chest are microscopic particles of magnetite, which can be used to locate the earth’s magnetic field. The monarch’s navigation system enables it to migrate to a new location 3,000 miles away to an accuracy of plus or minus 100 feet. The monarch butterfly is designed to migrate.

Besides the specially designed navigation system, the fully grown monarch butterfly has several other fascinating design features. For example, the caterpillar goes into the chrysalis stage completely blind, having thrown away its six simple eyes, which could only see black and white. The butterfly emerges with two new compound eyes that can see every color that a human can see plus ultraviolet light. Each eye has 6,000 lenses or simple eyes. The lens system allows the monarch to see in all directions simultaneously. The monarch’s eyes are the most elaborate and complex in all the animal kingdom. It can see objects up close as small as .04 inches and large objects, like humans, 20 feet away.

Also, the two antennas on the monarch’s head are very important. They are used to balance the butterfly as it flies. Removing one antenna causes the butterfly to fly in circles. On the tip of each female’s antenna is a red smell sensor capable of smelling the male monarch’s flowery perfume as far as two miles away.

Before the female monarch lays its eggs it tests the plant leaf to see if it is suitable. It taps the leaf with its two forelegs and uses six sharp microscopic needles on its forelegs to break the leafs surface causing juices to exude from the leaf. The two antenna are lowered at the same time to smell the leafs juices and the tastes sensors on the bottom of the other four legs are used to determine if the leaf is a suitable place to lay her eggs. These taste sensors are 2,000 times more sensitive to the taste of sugar than our human taste buds. If the eggs are laid on the wrong type of leaf there would not be another generation of monarch. This design feature had to be right the first time. There was no time for an evolutionary process.

The monarch butterfly has four wings. On these four wings are about one million scales. Each of these scales are filed with air, giving them a low density, which enables the butterfly to fly more easily. The monarch cruises at about 10 miles per hour, but can fly as fast as 30 miles per hour in still air. Though the monarch will usually fly close to the ground they have been seen at altitudes as high as 12,000 feet.

The amazing capabilities of Monarch butterflies. Evolution, or design ?

How and why should Monarch butterflies have evolved a magnetic compass as navigating tool, and migrate 2,000 miles to overwintering sites ? Thats not a behavior needed for survival, since its a unique remarkable behavior amongst butterflies.

Monarch butterfly uses magnetic, Sun compasses, study finds - June 24, 2014
Excerpt: monarchs use a light-dependent, inclination magnetic compass to help them orient southward during migration.,,,
"Our study shows that monarchs use a sophisticated magnetic inclination compass system for navigation similar to that used by much larger-brained migratory vertebrates such as birds and sea turtles."

Monarchs use a time-compensated sun compass in their antenna to help them make their 2,000 mile migratory journey to overwintering sites.,,,
Using flight simulators equipped with artificial magnetic fields, Patrick Guerra, PhD, a postdoctoral fellow in the Reppert lab, examined monarch flight behavior under diffuse white light conditions. He found that tethered monarchs in the simulators oriented themselves in a southerly direction. Further tests in the simulator revealed that the butterflies used the inclination angle of Earth's magnetic field to guide their movement. Reversing the direction of the inclination caused the monarchs to orient in the opposite direction, to the north instead of the south.

the monarch’s brain (the size of a pin head) interprets 72,000 electrical pulses from the eyes to translate the picture the butterfly is seeing. It also computes the angle of polarized light that it sees to determine the sun’s orientation and it’s position on earth. Inside the monarch’s brain and chest are microscopic particles of magnetite, which can be used to locate the earth’s magnetic field. The monarch’s navigation system enables it to migrate to a new location 3,000 miles away to an accuracy of plus or minus 100 feet.

To test the light-dependence of the monarch's magnetic compass, Dr. Guerra applied a series of wavelength blocking filters to the lights in the simulator.,,,
These tests showed that the monarch's magnetic compass, and thus directional flight, was (also) dependent on exposure to light wavelengths (380nm to 420nm),,
Together, these results provide the first demonstration that the monarch butterfly uses a light-dependent, inclination compass during its long journey. It is also the first evidence of such a navigational tool in a long-distance migratory insect.

Furthermore :

The monarch butterfly has four wings. On these four wings are about one million scales. Each of these scales are filed with air, giving them a low density, which enables the butterfly to fly more easily. The monarch cruises at about 10 miles per hour, but can fly as fast as 30 miles per hour in still air. Though the monarch will usually fly close to the ground they have been seen at altitudes as high as 12,000 feet.

The monarch butterfly is designed to migrate.
