Tiny olive mayflies can hatch any time of year, but are especially common in late fall. When trout eat these annoying little bugs, at times they won’t take anything larger than a size 24. But these flies are easy and simple to tie. You can do it! Watch how simple and easy these tiny imitations are to tie–in fact we’ll have time to tie both a dun and a spinner.
