Name that fly, or flies

[stuartp]

I am hoping someone can help me out here, I was given these flies to try out.
They proved very successful indeed and the person who tied them promised to send me the details.

That never happened, so I am left wondering if they have a name or did he just make them up? and what the foam material is? and where I can get it from?

Sorry for all questions, I am hoping someone more experienced than me can fill in some of the blanks.

The yellow version as deadly for browns in the river we were fishing and I am going back in June so I would like to tie some up beforehand.

The bald one lost it's deer hair after catching a good few fish, but I have included it so you can get a better look at the foam.

look like caddis emergers. the foam is likely to be closed cell ethafoam, you can get it at most fishing shops that sell tying gear. looks like he just thought of them himself?

Thanks for the reply, they are efeective but very crude looking flies, he is far more into his micro sized Grayling flies and doesn't dedicate much time/effort to the Browns. I will get hold of some of that foam and see if I can't do a better job!
