SWIFT SETWING, ELFIN SKIMMER, AND DOT-TAILED WHITEFACE

Male Dot-tailed Whiteface. The only place I have found this species is at Cedar Bog near Urbana. This species is more common in northern Ohio; the Dayton area is actually near the southern limit of their range. Historical records indicate that they used to be more common in southern Ohio than they are now. 

Female Dot-tailed Whiteface. Dot-tailed Whitefaces fly in late spring and early summer.

Female Elfin Skimmers have a wasplike appearance. These tiny dragonflies can be found at Cedar Bog from late May through July, but only if you have good eyesight!

Elfin Skimmers are North America's smallest dragonflies, and they are classified as an endangered species in Ohio. Elfin Skimmers are found at only a few locations in Ohio. One such location is Cedar Bog, Urbana, where this male Elfin Skimmer was photographed. You need to look very hard to see these tiny gems. (The first time I saw an Elfin Skimmer, I thought he was a "fat" damselfly because he was so small.) 

Swift Setwings are typically a species of the southern U.S., but they are expanding their range northward. They were first discovered in Ohio in 2014, at a site in Champaign County. I found the individual at left at Spring Lakes Park in Bellbrook (Greene County), on July 17, 2016. I saw another Swift Setwing at Spring Lakes Park on July 9, 2017, in the exact same willow as his predecessor the year before! They have been showing up at scattered locations all over Ohio ... but sadly, I have not seen any Swift Setwings at Spring Lakes since 2017. 

Elfin Skimmers live in bogs and fens. Their demanding habitat requirements are part of the reason why they are so scarce.
