Quick trip to Crosswinds Marsh

Darner!

Yesterday afternoon, Jorie and Stephanie accompanied me for a short visit to Crosswinds Marsh (CM) in Sumpter Twp., in SW Wayne County. CM is not a naturally-occurring marsh, but is a mitigated wetland that was constructed in the early 1990's as a result of the expansion of Detroit Metro Airport. There are approximately 900 acres of habitat connected by a series of beautiful boardwalks that interconnect over the water. It's a very visually appealing place, though the large landfill to the east is a bit disconcerting, and of course, there are big jets in the air at all times, as they come in to Detroit Metro. If you can sort of blot out the jets, the marsh is a very nice visit. Yesterday was my first time there, and though not exactly a collecting trip, I was interested in seeing what it might be like for future trips when odes are about. Though it was sunny, it was only about 68°F and the best days of dragonflies are long behind us. However, we did see lots of Sympetrum vicinum, which will be around until the hard frosts finally do them in. As we were walking back along a trail that skirts the edge of the woods, Marjorie spied a darner getting some sun on the trunk of a tree. After she took a series of photos (above), I tried catching it by hand. I almost had it, but was not aggressive enough it it barely got away. From what I can tell, it looks like Aeshna canadensis. Crosswinds is actually an easy drive from Ann Arbor, so I will be out there again next season, and see if I can find something that Julie and Darren haven't yet seen. :D

Am I going to have to get down there and catch one? Where in Crosswinds did you see this Aeshna?
