Help with bug ID

[limestone]

Can you ID this bug? I've found a few of these under rocks on a local spring creek. I looked around troutnut.com couldn't find anything that looked like them. Attached is a (crude) drawing of what they look like to the best of my recollection. I have found have found them in sizes 14 and 16. They have flat, segmented backs, and a tail that reminds me of a lobster's. Obviously, they're brown, but their underside is all white, and they have tons of little white legs. They seem like great trout food.

Your drawing is of little help, but based upon the rest of the info, I am going to guess it was a scud (freshwater shrimp):

What about cress bug?

 

[tomgamber]

That might work too...

Cress Bug! Thats what it was. Thanks

I did some research on cress bugs, apparently they are little crustaceans, aquatic versions of rollie-pollies.

Can anyone recommend a good cress bug recipe?

Also, I attached a picture a huge ocean dwelling relative of the cress bug.

My cress bug recipie isn't the easiest to tie, but with a little practice is a pretty effective pattern.

Hook: Size 16 straight shank of caddis curve (preference)
Thread: Brown 6/0
Lead: .25 tied to each side of the shank (this takes a little practice and correct thread tension)
Rib: Brown rod winding thread (3/0 would work) OR fine copper wire
Body: Mix of brown and grey dubbing (match your samples from your stream) (Spring Creeks are a littel more grey than the picture) Dub to the head and back very thin and very tight. On the 3rd pass, back to the head, a normal amount of dubbing (maybe on the sparse side) still very tight. Once finished dibbing, rib the fly with even segments, at least 6-7. Tie or ribbing material and finish the fly.
Then, using a stiff bodkin or T-needle, pick out the last layer of dubbing ONLY sticking the needle from the back and picking straight out. Pick out both sides. After all picked out. trim the dubbing with sharp scissors. This gives the fly the edges of the segments and a flat appearence.

How about the Ray Charles. A very easy tie that works well here as well as many rivers and streams out west. Check it out.
