Some researchers have pinpointed geographical footprints in monarch butterfly wings that have led to locating where monarchs migrate every fall in North America. Even though the butterfly's origin was discovered to be widespread across Canada and the United States, the majority of monarchs migrated from the American Midwest to Mexico. In the recent years, researchers have observed a decrease in the monarch population, which could be due to a numerous amount of factors. eradication of milkweed, which began in the mid-1990s. Monarchs feed on milkweed and lay their eggs on the plants. "We're facing a growing crisis of species extinction, not just with monarchs," said Norris, co-author of the new paper.
I personally believe that it is important for such an iconic species like the monarch to gain recognition and help in sustaining their population. With this new "chemical footprint technology" I think that it will become easier to learn more about the species and figure out ways to avoid their endangerment. https://www.sciencedaily.com/releases/2017/01/170110161022.htm
