Another phenomenal pattern developed by the late Gary LaFontaine, author of the book Caddisflies.  He did exhaustive research on Caddsflies and their behavior including many hours scuba-diving in riffles, lying on his back and looking up during a Caddis hatch.  To imitate the translucency of emerging Caddisflies, he developed patterns that incorporate a veil of Trilobal yarn to simulate the bubble of air produced when they emerge.  The Deep Sparkle Pupa (DSP)  is an important nymph incorporating this design, and we have a recipe for that wonderful fly down the list a ways.  The Emergent Sparkle Pupa (ESP) is the floating version.  To make the veil, tie in a clump of yarn on the bottom and one on top of the shank, at the hook bend.  Spread the fibers around a bit, to encircle the shank, then cinch up tight.  Dub a tight underbody, then gather the yarn and pull it forward, and make a couple wraps over it.  With a bodkin, pull out the fibers to create the veil and then cinch up the front wraps.  Tie the wing in similar fashion to an Elk Hair Caddis.  Z-Lon can be substituted for Trilobal yarn, but lacks the same sheen.
