Rather than emerging mid-stream like many other mayflies, Ameletus emerges by crawling out on stream side rocks - making the dun stage of the hatch unavailable to feeding trout. Dry flies and emergers are not the way to go during an Ameletus hatch.

(note the dark wingpads that are characteristic of a mature nymph)
If you look at the nymph in the above picture and compare it to a Pheasant Tail nymph, it is almost a perfect match. Drifting a Pheasant Tail (size 12 in the spring, and size 14 in the fall) will usually connect you with a few fish on those cool slow days. And aggressive line mending makes the fly move in short spurts characteristic of Ameletus attempting to swim to safety.
So, why bother learning the names of the bugs that hatch on your local waters? Quite simply, knowing what genus or species you are dealing with open the door to a wealth of information that greatly narrows down fly selection and tactics. It's all part of the formula of matching the hatch.
