The lake was glass and the rainbows were slurping backswimmers and boatmen off of the surface. I smiled. I tied on an Ultimate Boatmen and had a great day connecting with rainbows on the surface. Ultimate boatmen are a bit tedious to tie but they are a great imitation of a backswimmer. Casting at rising rainbows with my imposter yielded some heart stopping strikes by aggressive rainbows.

Here are some backswimmer imitations that were shown to me by my buddy Rick. These patterns are so effective.
2mm foam, some black dubbing and black silly legs make for a great pattern
