This is some type of Mayfly, seen along with many others, one early rainy morning on the exterior posts of our motel in Standish, Michigan Michigan, June 2019
This dragonfly was a new one to me, resting on a small boardwalk on a forest trail in Michigan. It's markings were so distinctive I was able to find it in my field guide. There were lots of dragonflies in some areas, many of them small and flying rather than resting. Michigan, June, 2019
