The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Here's a "water penny" (a Psephenidae beetle larva) crawling around on a real penny.

I'm pretty sure there are no current flies tied specifically to imitate the Water Penny. I really don't know if they are a significant food source to trout. If I was to tie one I would just use a pair of those round Velcro tabs about 1/2" in diameter and put one tab on the bottom of the hook shank and add some glue and put the other half on top and press them together so the Velcro hook and loops mesh and the glue is distributed well. After the glue dried I could color the top and bottom with various waterproof pens and trim the diameter to match the size of the natural.

Like many flies, my musings on a water penny larva fly was more about a fly for the fisherman than perhaps for the fish.

Now that I've had time to think about one, I am thinking about a round tab of brown leather (I have some from an old jacket) over a bit of light brown / white mohair mix.

I could envision a trout downstream of a disturbance of the stream bottom, caused by wading fishermen or a herd of deer, slurping up some random water pennies dislodged from their attachment to gravel and rocks.

Adding a pattern on top made by waterproof pens as Wbranch suggests would be a nice finishing touch.
