Butterflies are some of the most beautiful in...

Butterflies are some of the most beautiful insects in the world. However, what interests the scientists most is not their fascinating looks, but how they sense nature. They use their senses of sight, touch, hearing, smell and taste to find food, lay eggs in good places and avoid hungry enemies.

Butterflies have large compound(复合的) eyes. No matter where the things are, they can see them without turning their heads. 1. They are more possible to notice a sea of flowers than a single plant. Butterflies do not "see” colors. They are color blind.　 2.The light on many flowers guides butterflies to honey.　　　

How do butterflies smell? Butterflies have a very well-developed sense of smell, but it is not in their noses, since they don't have one. Sense organs (器官)are in their feet, and many other parts of the body.3.

Do butterflies use their mouths to taste the food they find? Not really. Butterflies' feet have sense organs that can taste the sugar in flower honey. They let the butterflies know if there is something delicious. 4.They feed their babies using a long tube(管道)，and they get all their food from this tube as well.　　

Butterflies don't have ears. Instead, they “hear" sounds through their wings by sensing changes in sound vibrations(震动).Butterflies' body is covered with sensory hairs. 5..For example, the hairs give butterflies information about the wind when they're flying. And where there is rain, the hairs can also tell butterflies.　

The scientists say that butterflies may have senses we don't even know about yet, because their body is very different from ours. Therefore, it is difficult to understand when we use our own human senses to study it.　　

A. Like most insects, butterflies are very nearsighted.　　

B. They can let butterflies feel the environment around.

C. So it is not difficult for butterflies to find flower honey.

D. But they can sense sunlight, which tells them the direction.

E. They can help butterflies find their favorite flower honey food.

F. Some female butterflies taste the plants carefully to find places to lay eggs.

Monarch butterflies from eastern Canada make the most amazing journey in the insect world. Each year, this butterfly travels about 3000 miles to its winter home in central Mexico. How can it fly so far? And why does it make this long and dangerous trip? Scientists still don’t have an answer.

For many years, people in Mexico wondered where the orange-and-black butterflies came from every winter. Then, in 1937, a scientist started to follow and study the butterflies. For the next 20 years, he discovered that one butterfly started its journey in Canada. Four months later, it arrived in Mexico.

The length of the butterflies finds their way back to the same place? Another amazing thing is that the butterflies always return to the same area in central Mexico.

How do the butterflies find their way back to the same place? This is an interesting question because only every fourth generation（一代）makes the trip south. In other words, the butterfly that travels to Mexico this year is the great-great-grandchild of the butterfly that traveled there last year.

Each year, four generations of a Monarch butterfly family are born. Each generation of the family has a very different life. The first generation is born in the south in late April. It slowly moves north, reproduces, and then dies. On the trip north, two more generations are born, reproduce, and die. Each of these generations of butterflies is born. This generation has a much longer life. It lives for about eight months. This generation of butterflies makes the amazing journey back to the winter home of its great-great-grandparents. The butterflies spend the winter there, and in the spring they reproduce and then die. Their offspring will be the first generation of the next circle of life.

Today, people are still studying the Monarch butterfly. But they are not clear about everything.
