June 7, 2013 — Waukesha County

Southern Kettle Moraine State Forest-Mukwonago River Unit. Formerly this was the Rainbow Springs Golf Course along hwy. LO east of hwy. E in extreme southern Waukesha County.

Ashy Clubtail (Phanogomphus lividus)
I believe the species is correct, but I am a beginner at this. I have more photos if needed for identification.
