The flies i think you are looking at are a foam back emerger i tied for a guy going to the Green...he had me tie 12 dozen, those are just leftovers ive never really fished too much. he liked them though, hence having me tie so many. the ones next to them are just variations of the Hurricane midge alot of guys fish on Grey Reef...red seems to be a popular color. All the flies in that box are for the North Platte, although i usually end up fishing the amber scuds, red tube midge, and the sow bug mostly on that river. The guy whom tied you the ones at Two Guys use the sow bug alot, (origionally tied by a guy named Honny, a local) I know this because i used to work at Two Guys and still fill in on occasion and we sell a lot of those patterns.
