The tiny mayflies of this family are usually found in warm, slow, marginal trout water, although some trout streams hold good populations too.

The only genus ever known to produce fishable hatches is Caenis. It turns up frequently for anglers who sample nymphs, but it is rarely of any practical importance for fly fishing because its emergence traits and tiny size (even smaller than Tricorythodes) make it relatively unimportant.

Brachycercus is even more focused on warm water than Caenis.

Latineosus, Sparbarus, Susperatus should all be included in the genera that aren't included (I think).

Jargon Defined:

Emergence: The transformation of a nymph or pupa into the adult winged stage of an insect. The term may refer to the emergence of an individual, or the daily or yearly event in which all individuals of a species emerge.

Nymphs: The juvenile, underwater stages of mayflies, stoneflies, dragonflies, and damselflies and other aquatic insects whose juvenile stages are covered by hard exoskeletons. The word can also refer to the fishing flies which imitate these creatures, in which case it is used as a blanket term for flies imitating any underwater stage of an invertebrate (except for crayfish and leeches).
