March Bubble Wet

March Bubble Wet tied by Darren Dunbar

The March Bubble Wet is inspired by Ralph Cutter's adult diving patterns. Cutter suggests that many adult caddis and adult mayflies either swim or crawl below the water surface to lay eggs. Cutter notes that "their respiratory systems require free oxygen, so the insects carry an air bubble (called a plasatron) with them as they prowl about underwater)". While I concur with Cutter's findings, I also believe that there is strong evidence of an air or gas bubble present at mayfly or caddis emergence. This phenomena is illustrated in the late Gary Lafontaine's  ever-popular book Caddisflies. In a nutshell, Gary opined that a the caddis emergence entails a gas bubble inflated within the caddis pupal skin, which aids in the ascent to the surface.

While there is not a clear picture of what exactly this gas bubble looks like to the trout, we may only assume that there may be a flash of light that keys a trout into a pupa feeding frenzy. For me, the March Bubble is not just a simple wet fly with an over-sized attractive glass bead. The bead not only creates some enticing flash, but helps set the hackle into an attractive splay that is entirely effective.  Other key components of the fly include: a bright yellow DMC Floss rib that illuminates some segmentation; and a tapered clear UV finished body, which aids in an increased sink rate and adds some durability.
