The size of the dry fly hook will depend on how big the tricos are on your stream. Maybe anywhere fr #18 to # 26.
Early in the season, the trico size is a little larger. But as the season goes on - the size will get smaller -#26
The female has a white body, very slim. The male has a black body, very slim. The thorax is usually black and on the meaty side.
Wings are spent and can be anything fr CDC, feather tips or plastic. Its what you can tie the best with. Females have two long tails and males have two shorter tails. Females fall usually first, then the males. You have to see what the trout are on to.
Tippets down to size 7x or 8x, esp when the trout are finicky.
Pick a fish thats working and keep casting to about a foot in front. Try and pattern the fishes rises.
Tight lines and many hook ups
