Because the Caddis flies start to fly all around here is an emerger that work here  in Eastern Europe and I have no doubt that will work everywhere:

For tying these flies I use:

-Demmon BL hooks

-Trout Line Super Selected CDC in olive and tan for body

-Underwing: TroutLine Khaki Campbell CDC

– Deer Hair for wing

-UV Ribbing quill for ribbing the body

Happy tying
