The epic migration of this butterfly is written in its chemistry
Painted women travel to the world on a large scale every year – including Sahara
Painted women are butterfly the world’s ultramaratoners – even more than the emperors. Scientists have long known about their globotrotting trends, but have recently focused on their exact migrant routes.
For many generations, butterflies can fly up to 9,300 miles annually from Scandinavia to equatorial Africa and back. Although not every painted woman travels widely, researchers have recently expanded In PNAS Nexus That some individuals fly up to 2,500 miles from Europe Overwintering ground In African Sahel, traveling on the Mediterranean Sea and Sahara Desert On the way. Anything unknowingly Cross the Atlantic Ocean For South America, other researchers found. In North America, meanwhile, women painted between Mexico and Canada. In Asia, he has also been seen cutting through the Himalayas.
“They are not inactive riders on the air,” Arthur M. Shapiro says, an emeritus leopyist at the University of California, Davis. “They are directing themselves.” In a state of ideal reproduction, “the air is completely full of them,” he says.

Low weight than one gram, painted women are very light for pasting traditional tracking devices. For new studies, Ecolaxist Megan S. of Ottawa. Reich and his colleagues captured 40 butterflies and understood the variants of chemical elements, or isotopes on the basis of isotopes. Hydrogen and Strontium Finding those who run for a long time in their wings.
“Sometimes people think of butterflies as a truly delicate, almanac creatures,” says Reach. “But they can be quite rigid.” Painted women are well suited for long distance travel. No matter that the location, innumerable host plants provide them food. When it cools down, they tremble to produce body heat. Their triangular predispositions increase them up to 30 mph. Powered by yellow fat reserves, they can fly so high, by the 2000s, people in Britain virtually Never left them leaving them The country and therefore thought that they must have been dying from every winter.
Still painted women are not unique. Hundreds, if not thousands, are most likely for insect species, then stay with dragonflies Cross the Indian OceanKites Traveers Australia And plant hopper Windsurf through East Asia“Some incredible insects are migrates,” Rich says, most of which are never recorded.
