When stoneflies re-enter the food chain

Hi All,

On the stream I fish on, when the stone flies skitter
across the water to lay their eggs, they frequently loose
control and get stuck prostrate on the surface. Thus,
re-entering the food chain, much to the delight of the
local rainbow trout population. (Their strikes on them are
rather spectacular.)

Does anyone have a favorite pattern to simulate this?

Many thanks,
