Common Green Darners Migrating South

Monarchs aren’t the only insect that are seasonal migrants.  The Common Green Darner dragonfly and a few other dragonfly species are as well.  However, where Monarchs move northward in the spring over several generations, one generation of Common Green Darners flies all the way from southern U.S., Mexico and the Caribbean in the spring to New England and Canada.  Here they lay eggs which give rise to a second generation that migrates south in September and October. Upon reaching their destination they then breed. A third generation emerges around November and lives entirely in the south during winter.  It’s their offspring that start the cycle again by swarming northward as temperatures warm in the spring.
