Cress Bug by Big Y Fly Co.
Cress Bugs, also known as Sow Bugs, are a vital food source in aquatic environments where they are found. They are available year-round, making them a reliable feeding option for trout even during winter months.
These imitations are lightly colored with an olive/gray blend and combed out to mimic the natural texture of a real sow bug, giving fish the impression of legs or a live insect.
The flash is folded over the back to create a shiny, shell-like appearance that enhances realism and attraction to trout.

The Cress Bug worked well in a cold spring stream. Trout took them immediately, even on a dull day. The texture and color matched the real bugs perfectly.

Great addition to my fly box. The imitation is durable and looks authentic. I caught several trout with it on a slow day.
