"These little critters supplant the importance of many other well-known mayfly hatches."
-Fred Arbona in Mayflies, the Angler, and the Trout
Arbona did not overestimate these critters. Their great numbers and multiple broods each season make up for their size, which is rarely larger than size 16 and often smaller than size 20.
Hardly mentioned in angling literature prior to the middle of the last century, baetids have become increasingly important to anglers, rivaling any other family of mayflies in this regard. This is largely due to the extension of fishing seasons that now include the early and late periods when this family’s species usually dominate hatching activity. Another important reason is the tremendous improvement in tackle allowing more practical imitation of these little mayflies. The dramatic ecological changes in many of our watersheds and the subsequent impact this has had on the makeup of taxa populations is also a factor.
Taxonomically speaking, this is a most unruly family. The entomological community seems to be perpetually reclassifying its genera and species to the chagrin of many anglers. These changes are not capricious. The reason is older nomenclatures haven't provided the taxonomic flexibility required as more becomes known about the complexities of baetid relationships. Classification of this family’s genera and species is very much a work in progress. The changes have been so extensive that it is beyond the scope of this hatch page to track the taxonomic history effectively without interjecting even more confusion. If you are frustrated by the inability to find some of the old familiar names, you're not alone. Rest assured these popular hatches are listed here, just under the latest classifications. The old famous names are referenced in their hatch pages.
Common baetid hatches with a national distribution are the species
Acentrella turbida,
Baetis brunneicolor, and
Baetis tricaudatus. In the West,
Baetis bicaudatus,
Diphetor hageni and
Plauditus punctiventris can also be common. In the East and the Midwest, look for
Baetis intercalaris and
Plauditus dubius. The species
Iswaeon anoka is important in both the West and Midwest. Some of the
Procloeon and
Anafroptilum (prev. Centroptilum) species are coming to the increasing notice of anglers across the country.
Stillwater anglers are likely to run across
Callibaetis ferrugineus ferrugineus in the East and Midwest. Western anglers will find
Callibaetis californicus and
Callibaetis ferrugineus hageni to be very important.
Streamside identification of these mayflies to specific and often even generic level has always been difficult. This is now even more so as new taxonomic evidence has shown hind wing conformation (or lack of hind wings) and other features are less dependable as ways to tell the genera apart. Many of the lesser-known species probably produce excellent local hatches but have not caught enough attention to be properly recognized by anglers. The lesson is that we should not assume anything about the identity of many
Baetidae hatches we come across; they may not even be in the
Baetis genus, let alone familiar species.
