To say that a bull Bluegill ?rises? to take a fly would be misleading at best. If you have ever watched a trout approach a drifting fly, then after scrutiny open its mouth to sip it in leaving a tell-tale rise-form. That?.is a rise. A big colored-up bull Bluegill on the other hand attacks a fly, porpoising over it in a way that will not only suck in the bug, but kill it in the same motion. They can at times put the surface take of a largemouth bass to shame, leaving you in astonishment to find that it?s not a 3 pound bass on the end of your line, but rather a 12 inch bluegill with shoulders an inch wide.
