Shut Highway for Butterfly
After the last cold current bugle in every spring, Butterfly-March begins to depart from south to north inhabitant, where they breed and die in summer bright sunshine--death and hope occur in moment.
The National Freeway Bureau shut highway for purple milkweed butterflies to cross about two hours yesterday to test the function of the whole program. In scientist's initial observation, when The Bureau shut outlane, there are about 70% of butterflies would fly higher to cross highway, but 30% of butterflies could not make it and hit by passing car at inlane.
When the number of butterflies arrive 2000 in one minute, a lane in a major Taiwanese highway will be closed, protective nets and ultra-violet lights will be used to provide a safer journey for over a million migrating purple milkweed butterflies. Yesterday the number of butterflies already arrive 300 in one minute.

Because butterfly needs to absorb sufficient sunshine energy to flutter its wings, there is no sufficient solar energy for this at night, so butterfly rests at night. Then, why using light at night?
