Researchers have found a faster way to study the spread and diet of insect pests. Using a technique called DNA barcoding, which involves the identification of species from a short DNA sequence, they studied populations of numerous moth and butterfly species across Papua New Guinea. DNA barcodes showed that migratory patterns and caterpillar diets are very dynamic.
