Learn About Sow Bugs
I was looking for a good Sow Bug pattern today and I found one at http://flytying123.com
Rainbow Sow Bug
Sow bugs (Isopoda) are not found in every river, but when they are present you can bet the fish love them. The rainbow sow bug is my favorite variation, and has produced very well for me on every river I fish that is home to sow bugs. This is a simple pattern that has only a few steps and materials involved. Don’t let the simpleness of this pattern fool you. Tie, try, and simplify your ways of catching fish with sow bugs.
