One kind of female butterfly mates only once in its life -- and then closes its wings to avoid "harassment" when pursued by persistent and unwanted males, a Japanese researcher said.

Observations of the Small Copper Butterfly, a colourful orange and black butterfly, showed that some females closed their wings when males flew by, but only when they were males of their own species, said Jun-Ya Ide, an associate professor at Kurume Institute of Technology in Fukuoka, western Japan.

"When we looked into why, the males were courting the females. They do this very stubbornly, so the females sometimes try to get away -- or prefer to stay unobserved," he added.

Ide and his colleagues brought a model of a male butterfly near the females to test their reactions and found that young females that had yet to mate kept their wings open, but those that had already mated closed them.

Not only can the persistent attentions of unwanted suitors harm the delicate females, fleeing from them -- with the male often in pursuit -- uses up strength and can even shorten their lives, he added.

"Closing their wings makes them less visible, helping them avoid communication with their own species. We figured they were trying to avoid harassment by males," Ide said.

The most famous statue-the Sphinx in Egypt has been damaged. The experts are trying to find out the cause to protect it.
As we all know, the Sphinx has the body of a lion and the face of a man. It was cut from limestone(石灰石) near Egypt's pyramids about 4, 500 years ago. Not long ago a large piece of stone fell from the Sphinx's right shoulder.
In order to protect the statue from more harm, a computer was placed on it to measure rainfall, wind speed and air temperature. The computer also measured the amount of water and air pollution, the direction of wind and the temperature of the statue itself. The effects of age, wind, water and pollution have greatly weakened the Sphinx. Sunlight, wind, water and pollution have been eroding the outside of the statue for centuries. The experts hope that the information from the computer will help protect it from more damage. They say the more they know about what is destroying the Sphinx, the more they can do to protect it.
