Waterbugs include (10) aquatic families.  However, waterboatmen and backswimmers (illustrated above) are the primary families of interest to trout, particularly in stillwaters.

Waterboatmen and backswimmers are similar in size and shape, and both have oar-like hind legs.  Waterboatmen have a more flattened body and a drab body color.   Backswimmers tend to have colorful body patterns, and as their name indicates, they swim backside down.
