More dragonflies and damselflies

I had a very rare thing happen today; that is, no pre-planned events or other things to do.  I managed to get all of my errands done yesterday and even had time to visit a friend's cottage in Washtenaw County.  I asked Julie Craves for some nearby places to take photographs of odes. She suggested two, Crosswinds Marsh and the hockey ponds at Lower Huron Metropark.  I visited both this morning.

I used to go to Crosswinds Marsh all the time, but it's been years since my last visit.  I'm glad I went.  It was super hot and breezy, but still seemed good to see dragonflies.

First I was distracted by a huge garter snake sunning at the start of the Bald Eagle trail and I regretted being unprepared with my camera. Then I was distracted by two birds. Try sneaking up on a kingfisher. Impossible! and you'll get an earful when they fly off.

Water lily


Michigan Rose flower


Male slaty skimmer (Libellula incesta)


Male common green darner (Anax junius)


Common milkweed

As nice as it was to walk around Crosswinds again after so long away, I didn't really see many dragons or damsels.  Widow and twelve-spotted skimmers and black saddlebacks flew by but clearly had no intention of perching so I gave up on them.  As for my photos, I worked hardest on the blue dasher but I guess I like the green darner photo best. Crosswinds Marsh has certainly grown up.  The boardwalks are a little aged and in need of repair in spots, but the vegetation is all grown up and is thick and full. I was reminded how, which some exceptions, it was never very good for bird migration.  But now it's easy to see and hear how good it has become for nesting birds.

From Crosswinds Marsh it's an easy and straight shot to Lower Huron Metropark.  It took me a bit of map studying to find the hockey ponds but more than well worth it.


This female Eastern pondhawk was flying around a large patch of green pond scum and tapping her abdominal appendage into the scum to lay eggs.  Though the video below is not great, and she is being chased by another dragonfly, you can still see a few seconds of the action.



Male widow skimmer (Libellula luctuosa)


Female Eastern forktail (Ischunura verticalis)


Male Eastern forktail


Male common whitetail (Libellula lydia)


Video of the completely different action of a female common whitetail laying eggs.


Of note, there were small fish in the hockey ponds.  I saw small catfish and I think I also saw striped bass (is this possible)?  Some of the fish were even trying to lay eggs (and being bothered by other fish). Nevertheless, clearly some of the ode eggs must hatch.


Thistle


Twelve spotted skipper (Libellula pulchella).


Female Eastern pondhawk (Erythemis simplicicollis)


Male Eastern pondhawk  


Another view of male blue dasher that shows wing shadowing or increased pigmentation at the tips.  I had read somewhere - unfortunately cannot recall source now when I need it - that this might be related to the age of the dragonfly.  I have since read an another article where this may be aberrant wing coloration.  


Another blue dasher


For the photo above and the four below, my first and best guess was female common spreadwing (Lestes disjunctus).  The habitat and color are right, but the abdominal appendage and the closed wings bother me a bit.  Also, in reviewing Nikula, et.al. and Paulson, females are very difficult to identify out of hand.  However, it is not a common spreading.  The possibility of a teneral bluet was suggested.  Likely to remain unidentified.







I was surprised that I did not see any female widow skimmers.  Widow skimmer males were chasing each other around as were male common whitetails.  I saw only one female common whitetail.  The egg laying [in video above] occurred immediately after a very brief copulation.  This was such a fun place to visit.  With a holiday weekend coming up I hope I can get back. And, I came away with only one tick!
