Today we have literally thousands of dragonflies flitting around our backyard near Lake Michigan. I did some research and identified
these large 3 inch green and purple dragonflies as the common green darner. These harmless but impressive dragonflies have a life cycle much like the monarch butterfly. The adults migrate south in the fall. The adults winter over in the south and then start a new line of offspring which slowly work their way north until a generation reproduces in our area. So these adults are no doubt starting their migration. We welcome them for the mosquitoes they are eating as they fly about our backyard.
