Catgut Caddis Pupa Cream

I've been tying and fishing this pupa nymph for over 10 years now. I was turned onto this material through the old euro nymphing forum Trout Predator Online and by Aaron Jasper who imported it under "bio-thread". 

Catgut is a very translucent material, and you can clearly see the flashy tinsel showing through here. Very buggy. 

Makes a great anchor nymph in larger sizes.
