Scientists have now found evidence that a group of the winged travelers flew over 2,600 miles (about 4,200 kilometers) across the Atlantic Ocean without stopping, according to a new study published June 25 in the journal Nature Communications.
The insects, which are not usually found in South America, were worn out with holes and tears in their wings.

The researchers hope to use the same techniques to investigate the migration patterns of other species of butterflies, she added.
