I saw these dragonflies on the trail in the vicinity of Wonderland Lake, just begging to be photographed. The picture above is the band-winged meadowhawk, as demonstrated by the brown bands on the wings. When I examined the photographs, I found that not all meadowhawks are alike. Below the fold, a dragonfly that to my eye looks identical, except that its wings do not display the brown, translucent bands.
Thanks to the experts at BugGuide for verifying the identity of S. obtrusum.
