Dragonfly migration explained for the first time ever - TomoNews

BALTIMORE — A team from the University of Maryland, Baltimore County is the first to determine the annual migratory cycle of the green darner dragonfly. According to the research published in the journal Biology Letters, researchers employed stable-hydrogen isotope analysis on wing samples of more than 800 dragonflies from eight different countries spanning 140 years. The wings analyzed were from specimens caught in the wild and from specimens preserved in museums. The researchers found it takes three generations of green darners to complete an annual migratory cycle. SOURCES: https://royalsocietypublishing.org/do... https://www.smithsonianmag.com/smart-...
