Insects Migrate in Wind Highways

from BBC News Online

Migrating insects use highways in the sky to speed their journey, according to a study published in Science magazine.

Researchers say moths and butterflies use sophisticated methods to find winds that will take them in certain directions for thousands of kilometres. The little creatures travel on winds of up to 100km (60 miles) per hour.

They use internal compasses to find these fast moving winds to carry them to their journey's end.
