Understanding the bug
As Chironomids are the same species whether in lakes or rivers (although in rivers they are referred to only as midges and for whatever reason thought of as a separate bug) larger imitations of the same patters you use in the South Platte or Big Thompson can be effective. It doesn’t hurt to tie in gills on these larger imitations as they can become a trigger for fish while searching them out. Many patterns incorporate a white glass or brass bead to imitate this quality with success. Keep in mind that even in size 8, it is still a midge and should be slender in profile respectively. Both straight and continuous bend hooks (scud bend) are used with success concurring with the ideal look desired by the tier or fisherman.
