Furled Extended Body Alternative
Damselflies are not a factor in the Northern Rockies freestone streams I focus on. So I have never seen, tied, nor fished a damselfly nymph.
But ducksterman's fly prompted me to do some reading about and look at a bunch of pix of damselflies, including the nymphs.
A furled extended body might prove an excellent alternative to the articulated body approach. An FEB would be cheaper, simpler, and have the advantage of better movement. And they are durable. I haven't had a problem with an FEB in the eight or nine years that I have fished a variety of flies based on the FEB platform almost exclusively.
The JARS FAOL FOTW for December 2012 and the Serendipitous PMD Emerger FAOL FOTW for May 2013 show and explain the technique for creating an FEB with incorporated tails. Combining the forward body of duck's articulated pattern and an FEB of light olive antron incorporating three pheasant tail fibers would probably make for very successful damselfly nymph pattern.

The fish are always right.
