平时,人们看到的蝴蝶都是三三两两地在空中飞舞,但是在有些地方,有时候会出现成千上万只蝴蝶大聚会的壮观景象。你听说过云南大理的蝴蝶泉吗?每年的农历四月,成千上万只蝴蝶飞到蝴蝶泉边,有的相互衔着尾巴,吊在树枝上,垂下一条长长的蝴蝶“链”,几乎和水面相接。如果身临其境,你会感到自己好像进入了童话世界。这是世界上著名的“蝶泉”景观。每当夏季,我国甘肃省榆中县兴隆山风景区,以及我国神农架旅游区的拜台沟,都会云集几十万只白蝴蝶,纷纷扬扬,像满天鹅毛大雪,充满那里的山沟。这是世界上有名的“蝶雪”景观。 Usually, the butterflies that people see are flying in the air in twos and threes. However, in some places, there are occasions where thousands of butterflies meet in spectacular ways. Have you heard of the butterfly springs in Dali, Yunnan? Every year in the lunar calendar, thousands of butterflies fly to the edge of the butterfly spring in April each year, and some of them hold their tails on each other, hang from the branches, and hang a long butterfly “chain”. It is almost connected with the water surface. If you are there, you will feel like you have entered the world of fairy tales. This is the world famous “Butterfly Spring” landscape. Every summer, the Xinglongshan Scenic Area in the Suizhong County of Gansu Province and Baitaigou in the Shennongjia Tourism Area in China will gather hundreds of thousands of white butterflies, all of which are full of swan and snow, full of ravines there. This is the famous “Snow Butterfly” landscape in the world.
