They are cold-water scavengers of dead plant and animal life, and they are extremely abundant in weedy spring creeks and many lakes. Their imitations make outstanding searching patterns (Searching pattern: Any artificial fly pattern used when trout that aren't feeding selectively on anything in particular. A searching pattern may be an attractor or an imitation of something specific that the fish might favor even though it's not currently hatching.), and work well fished dead drift or with a slow retrieve.
Where & When
Regions: East, Midwest, West
Preferred Waters: Best in alkaline (Alkaline: Having a pH higher than 7 (opposite of acidic). Moderately alkaline water is ideal for trout because it's better for the growth of phytoplankton, the usual base of the aquatic food chain, and that's good for the growth of everything higher up the chain, including trout.) water
Scuds are present year-round and are often the most abundant aquatic macroinvertebrate in their body of water. They do very well in both lakes and streams. They're generally associated with slow water and do seem to be the most common there, but some swift-flowing streams still hold good scud populations, and I've found them in the riffles.Preferred Waters: Best in alkaline (Alkaline: Having a pH higher than 7 (opposite of acidic).

I took this picture of a scud from above the water's surface in a very shallow, clear, tiny bit of water at the margin of a little spring pond.
