Researchers studying populations of numerous moth and butterfly species across Papua New Guinea have developed a new technique to study the spread and diet of insect pests--DNA barcoding, which involves the identification of species from a short DNA sequence. DNA barcodes showed that migratory patterns and caterpillar diets are very dynamic. In one case, a tiny moth that is distributed from Taiwan to Australia, had recently crossed thousands of miles of Pacific Ocean. The research is detailed in this week's edition of PNAS. read more
