Although these articles were from 2007, but its been practiced since by Taiwan eco department.
Its still relevant.  After all the depressed sharkfin, seal and other environment issues.  This is a feel good news to read.


每年春天,大批紫斑蝶在台灣南部度過冬天之後,北上遷徙繁殖,構成空中蝶河之壯觀景色。台灣當局今春首次決定間歇性封閉一條高速公路,給紫斑蝴蝶遷徙讓路。
BBC消息,每年大舉遷移的紫斑蝶,已經成群上路,台灣國道三號林內段是牠們必經路線;為避免北上紫斑蝶被車流撞到,高速公路局將在四月初紫斑蝶大量飛越國道時,採取間歇性封閉六百公尺北上外側車道。 此一「讓路於蝶」的生態保育做法,在台灣還是首例,全球也很罕見。 在這段全長六百公尺的公路上,封閉時間為每天上午9時至12時。高速公路局今後還將採取架設防護網以及在公路橋墩下安置紫外線燈管等措施幫助紫斑蝶安全穿越高速公路。 台灣的蝴蝶專家說,2005年春,他們曾經觀察到,每分鐘約有1.15萬隻紫斑蝶飛躍高速公路,形成一條壯觀的「蝶河」。 本月初,義守大學把蝴蝶保育學會的調查報告送交高公局,並建議「讓路」,被高速公路局接受。高公局長李泰明笑稱,今年清明節高速公路疏運計畫有兩套,一套給人用,另一套給紫斑蝶用。台官員承認,關閉一條車道可能會導致交通擁堵,但他們認為,為保護「蝶身安全」付出這筆代價是值得的。 安全遷徙 高速公路局的一位官員說,人類必須與其他物種----包括微小的蝴蝶在內----共存。 每一年紫斑蝶遷徙的過程當中,都有大量蝴蝶穿越公路時遭車輛撞死,大批蝴蝶飛越也威脅交通安全。 動物保護人士希望,關閉公路、架設防護網和安置紫外線燈管等項措施都可以幫助紫斑蝶安全抵達繁殖地。 安置防護網的目的是迫使蝴蝶高飛,避開車流。 因為蝴蝶有「趨光性」,不會選擇從橋下穿越。安置紫外線燈管是為了鼓勵蝴蝶改道橋下.

Highway shut for butterfly travel

Taiwan is to close one lane of a major highway to protect more than a million butterflies, which cross the road on their seasonal migration.
The purple milkweed butterfly, which winters in the south of the island, passes over some 600m of motorway to reach its breeding ground in the north. Many of the 11,500 butterflies that attempt the journey each hour do not reach safety, experts say. Protective nets and ultra-violet lights will also be used to aid the insects. Taiwanese officials conceded that the decision to close one lane of the road would cause some traffic congestion, but said it was a price worth paying. "Human beings need to coexist with the other species, even if they are tiny butterflies," Lee Thay-ming, of the National Freeway Bureau, told the AFP news agency.
Under the bridge
Each year thousands of butterflies die when turbulence generated by fast-moving cars drags them into the traffic or under the wheels of oncoming vehicles. Ecologists hope the triple-action effort of lane closure, protective nets and ultra-violet lighting will dramatically increase the milkweed's chances of reaching the breeding ground. The protective nets are designed to force the butterflies to fly higher, reducing the chances of them getting caught in the traffic. Ultra-violet lighting will be used below an elevated section of road to encourage the butterflies to head beneath. The measures are estimated to have cost $30,000 (£15,200).

紫斑蝶真的是圖片上那種藍色嗎??看起來真的很美,不過我印象中應該是咖啡色種帶點淡淡的靛紫色吧!!
