Sharonville SGA - Jackson County

Jackson County, Michigan, hasn't been thoroughly surveyed for dragonflies through the years.  I've scouted a few areas for odes and Sharonville SGA seems to have great potential with a variety of habitats.

On July 6th, 2014, I visited a couple spots in the State Game Area.

#1: Tamarack Lake has good-looking habitat for some less common odes.  I've also found Ostrich Fern here which may be a new location for the county and/or state. 

Tamarack Lake = Aug-2013

Almost immediately, there were two species which can be difficult to voucher.  A Prince Baskettail (E. princeps) and two or three Banded Pennants (C. fasicata).  The baskettail tends to fly continuously over open water and the pennant typically worked the edge of the vegetation out in the water.  Trying to take advantage of an incoming light breeze, I tried to position myself in a location where the dragonflies might be pushed closer to shore and if a "conflict" between them ensued, I just might get lucky to snag one or two species.  The boardwalk/dock only sticks out over the water by a few feet and the surrounding shoreline and lake bottom is deep muck and silt.  Thus, I couldn't wade out into the water without the risk of being swallowed alive.

Patience was key to wait for the right "gust" of breeze and aggressive interactions, but I was able to snag the target species.

Of course, during the interaction I made a misstep and sank in above my rubber boots.

I almost lost my boot in the muck.

#2: Forest clearings SW of Tamarack Lake and north of Lutz Road

I found this location to be great for individuals in the upland environment and if it's late in the season one can't complain about the abundance of blackberries to snack on.  In 2013 I saw a few individuals that I didn't get a chance to document.

It was apparently a Celithemis day.

This SGA will need additional visits in the future since there are more months and habitats to explore.

When Comet Darners Attack

Julie Craves, Mark O'Brien, and I made a visit to the Fox Science Preserve outside Ann Arbor on July 4, 2014.  Earlier in the season (late May) I found Painted Skimmers (L. semifasciata) which was collected for a second county voucher, many Carolina Saddlebags (T. carolina), and a couple Comet Darners (A. longipes).  This last species would be a new species for the county if we could voucher it on this outing.

Immediately on this 4th of July visit, we found additional Painted Skimmers and Carolina Saddlebags.  Shortly after looking for odes around the larger, deeper pond we had a male Comet Darner fly past.  These fast, strong flyers always seem to be just out of net's reach.  The water in the larger pond was a bit deeper than our rubber boots were high which prevented access to the entire area, unless we wanted to have wet feet.  This was a dry-foot day for me.

Mark O'Brien in the vegetation
We found a couple female Comet Darners apparently hunting or searching for oviposition sites.  The two locations frequented most often were separated by tall vegetation.  Mark stood in one location and I stayed in the more open area trying to inform Mark when a female was approaching his secluded section.  The female generally flew across the deeper water several inches above the water's surface.  She'd then fly through the vegetation (cattails, woody plants) at the same height. 

At one point, Mark yelled out and was swinging at a female that seemed to "attack" him in the midst of the vegetation.  Shortly, thereafter he emerged with the first county record of Anax longipes.

At one point during the afternoon we witnessed an interesting behavior of a male and female Comet Darner.  The pair was coupled initially, then the female flew across the pond seeming to act like the other female hunting for food or an oviposition site. At the same time, the male flew several inches behind her at or just above her height of flight, which was several inches above the water.  It was as if the male was guarding or protecting the female during her foray.
This was another successful outing within a few miles of our home and great to be in the field with another O'Brien of Washtenaw County.

DSA = 25 years !

Ladysmith, Wisconsin, was the place to be June 13-15, 2014.

 I combined attending this Dragonfly Society of the Americas meeting with the Ophiogomphus searches recorded in previous posts and followed by a quick family visit in western WI.

The meeting presentations were great with a variety of topics and the field trip locations provided access to great snaketail and clubtail habitat.  The Chippewa River just west of town was teaming with dragonflies.

Bryan Pfeiffer did a few blog posts noting finds and experiences of the DSA meeting here.

Others have much better photos than me, but here's a few photos of the target species at this location.  Of course, there were many other species flying in large numbers.

This male St. Croix Snaketail landed in a group of sunlit trees up the bank from the river.

 The location and community hosting this DSA meeting was very welcoming.  If one wants to find an abundance of snaketails, the Ladysmith area is highly recommended.

Ophio Odyssey - day 2, last stop #5

The Paint River - upstream

I had rainy weather continuing on June 12th, 2014, but tried to check another location that looked good for odes on the map.

5th stop = The DNR boat launch at the Paint River Forks (46.23134, -88.7188).

At this location, the north fork (left) and south fork (right) come together.

I spent most of my time on the south fork due to weather and found a few dragonflies.

Exuviae finds =

South Fork

1 Pygmy Snaketail (Ophiogomphus howei)

1 Riffle Snaketail (O. anomalus)

5 snaketail sp. (Ohiogomphus sp.)

1 Twin-spotted Spiketail (Cordulegaster maculata)

North Branch

1 snaketail sp. (Ohiogomphus sp.)

Unfortunately, this was my last stop before heading to the DSA meeting in Wisconsin the next day.  If time allows in the future, I'll definitely want to check this and the previous posts' locations for odes again.

3rd stop = Brule River at Hwy 73

This was a quick stop to check under the bridge (46.032529, -88.797263).

Exuviae found included 6 Ophiogomphus sp. and  3 Cordulegaster (likey maculata).

4th stop = Brule River at Hwy189

Another quick stop to check under the bridge (45.987746, -88.652184).

Here I found 6 Ophiogomphus sp.
