Last March, while at the Savannah National Wildlife Refuge, we saw Blue Dashers. These were our last dragonflies of our trip—days of rain and snow were to come. These dragonflies are common across most of the United States, except in the northern Great Plains. They do not like unvegetated shorelines. Blue Dashers are tolerant of poor water quality, a trait which probably contributes to their abundance.
We found this last Blue Dasher in June at the Lebanon Hills Regional Park here in Minnesota.
