Ophio Odyssey - day 1, stop 3


3rd stop = Deeper Flowing Water with Large Dragons

Erickson Boat Landing, DNR boat launch on the Paint River, upstream from Highway 141


MNFI found Ophiogomphus nymphs at the bridge of Hwy 141 (NW of Crystal Falls), but it was shaded in that area by the time I arrived on June 11, 2014.  I saw the sign to the boat launch upstream which was a few miles upstream and was pleased with the river access (46.14224, -88.40381).  


 The river was fairly wide (~80’) and ranged in depth from knee-deep to waist-deep with a moderate flow.
  

Dozens of teneral/young Swift River Cruisers (M. illinoiensis) with a couple of Prince Baskettails (E. princeps) were patrolling the river overhead.

 I have never seen so many Macromias flying in one place.  A couple of snaketails were observed, but too far away for a chance to ID.  At one point a female Twin-spotted Spiketail (Cordelegaster maculata) flew by and landed in a tree on the far bank.  
Upstream from the boat launch was a small woodland creek with a gravelly bottom and a few silty areas.  A couple of fast-flying dragonflies eluded me and remain a mystery.


In this location I also found some baskettails, including this male Spiny Baskettail (E. spinigera):


Only three exuviae were collected on the vegetation of the banks of the Paint River and the creek outlet.  These were the more common snaketails (O. rupinsulensis or carolus).

Unfortunately, this was the last stop with good weather.  The coming day called for rain, wind, and cooler temperatures.
