Overview

The Bloom Caddis is a high-floating dry fly designed for rough water. It features a dubbed body, deer hair wing, and a palmered hackle for buoyancy and durability. Tied on a standard dry fly hook, it often includes a dubbed thorax for added profile. The deer hair wing is tied down over the body to mimic the tent-like shape of adult caddisflies. It's a great pattern to practice stacking and securing deer hair while maintaining a slim body profile underneath.
