Fishing in lakes means buzzers. There are lot of models but why you shouldn’t try to tie a buzzer with catgut? Here is a model tied with red catgut biothread from Troutline. Looks normal when the material is wet but when gets wet looks really nasty! 🙂
And here the same fly but wet:
You can take catgut biothread in S or XS in natural color and with a permanent marker you can apply the color desired. It is easy and simple and it takes only a few minutes, not more than 3 or 4 to make on buzzer fly!
