The migration of this epic butterfly is written in its chemistry
Ladies traveling all over the world every year on huge trips – including the desert
Ladies are one of the most prominent world of butterfly – even more than kings. Scientists have long been known for their tendencies all over the world, but only recently the focus is on their accurate migratory methods.
For several generations, butterflies can fly to 9300 miles annually from Scandinavian countries to tropical Africa and return. Although not every lady has traveled widely, the researchers are recently detailed in PNAS Nexus Some individuals fly up to 2500 miles from Europe to Winter lands In the African coast, a trip over the Mediterranean and Desert Desert in the way. A few even unintentionally Crossing the Atlantic Ocean To South America, other researchers found. In North America, at the same time, the coated women flutter between Mexico and Canada. In Asia, they were monitored even in the Himalayas.
Arthur M. says M. Shapiro, an honorary Lepidopterist scientist at the University of California, Davis: “They are not negative contestants on the wind.” “They direct themselves.” In perfect reproduction conditions, “the air is completely full of it”, and he adds.

The painted women weigh less than a gram, and very light women so that they do not reach traditional tracking devices. For the new study, the environment world at the University of Ottawa, Megan Rish, and its colleagues, seized 40 butterfly and distinguished the places of its births, based on the variables, or isotopes, for chemical elements. Hydrogen In their wings-find the real real infiltrators.
“Sometimes people think about butterflies as fast -walled creatures,” says Reich. “But they could be very Hardy.” Ladies are especially suitable for long -distance travel. Regardless of the location, the endless host plants provide them with food. When the atmosphere becomes cold, they tremble to generate body heat. The triple introducing them to up to 30 miles per hour. Supported by yellow fat reserves, they can fly so high that until 2000, people in the United Kingdom are almost They didn’t notice them leaving The country and thus I think they may die every winter.
However, the ladies overlooking Leson Faridat.
