This topic is about the Insect Order Ephemeroptera
Mayflies may be the most important insects for trout anglers to understand. They are famous outside the fly fishing world for their fragile beauty and short adult lifespan, usually a single day to mate and die. The mayfly's poignant drama attracts poets and fishermen alike, but fishermen make the most of it. Read more...

| Pueblo Colorado Posts: 7 | Of the 4 main categories of mayflies (clingers, crawlers, swimmers, and burrowers) are there 2 tailed and 3 tailed mayflies in more than one category? Or are their some categories with both 2 and 3 tailed mayflies in them? For example: Do burrowers all have only 2 tails? | |

For example, in the Heptageniidae (clingers), Ironodes has two cerci, and Rhithrogena has three (as nymphs--adults can vary too). Baetis (in the Baetidae--swimmers) has species with two or three cerci, too. In short, most mayflies (nymphs) have three cerci, but individuals with two cerci can be found in several families. A better way to distinguish between clingers, etc. is by general body shape. | |

| Mercer Island, WA Posts: 483 | Ben-Of the 4 main categories of mayflies (clingers, crawlers, swimmers, and burrowers) are there 2 tailed and 3 tailed mayflies in more than one category? Yes, both clinger and swimmer mayflies have both 2-tailed and 3-tailed nymphal mayflies. For example: Do burrowers all have only 2 tails? No, all burrower mayflies are 3-tailed in their nymphal stage. Perhaps the following table will better illustrate this: Habit – Family – Genus (Nymphal Tails) Burrower - Ephemeridae - Ephemera (3) Burrower - Ephemeridae - Hexagenia (3) Burrower - Ephemeridae - Litobrancha (3) Burrower - Polymitarcyidae - Ephoron (3) Burrower - Potamanthidae - Anthopotamus (3) Clinger - Heptageniidae - Cinygma (3) Clinger - Heptageniidae - Cinygmula (3) Clinger - Heptageniidae - Ecdyonurus (3) Clinger - Heptageniidae - Epeorus (2) Clinger - Heptageniidae - Heptagenia (3) Clinger - Heptageniidae - Ironodes (2) Clinger - Heptageniidae - Leucrocuta (3) Clinger - Heptageniidae - Maccaffertium (3) Clinger - Heptageniidae - Rhithrogena (3) Clinger - Heptageniidae - Stenacron (3) Clinger - Heptageniidae - Stenonema (3) Crawler - Baetiscidae - Baetisca (3) Crawler - Caenidae - Brachycercus (3) Crawler - Caenidae - Caenis (3) Crawler - Ephemerellidae - Attenella (3) Crawler - Ephemerellidae – Caudatella (3) Crawler - Ephemerellidae - Dannella (3) Crawler - Ephemerellidae - Drunella (3) Crawler - Ephemerellidae - Ephemerella (3) Crawler - Ephemerellidae - Eurylophella (3) Crawler - Ephemerellidae - Serratella (3) Crawler - Ephemerellidae - Timpanoga (3) Crawler - Leptohyphidae - Tricorythodes (3) Crawler - Leptophlebiidae - Leptophlebia (3) Crawler - Leptophlebiidae - Paraleptophlebia (3) Swimmer - Ameletidae - Ameletus (3) Swimmer - Baetidae - Acentrella (2) Swimmer - Baetidae - Acerpenna (3) Swimmer - Baetidae - Baetis (2) Swimmer - Baetidae - Baetis (3) Swimmer - Baetidae - Callibaetis (3) Swimmer - Baetidae - Centroptilum (3) Swimmer - Baetidae - Diphetor (3) Swimmer - Baetidae - Heterocloeon (2) Swimmer - Baetidae - Plauditus (2) Swimmer - Baetidae - Procloeon (3) Swimmer - Baetidae - Pseudocloeon (2) Swimmer - Isonychiidae - Isonychia (3) Swimmer - Metretopodidae - Metretopus (2) Swimmer - Metretopodidae - Siphloplecton (3) Swimmer - Siphlonuridae - Siphlonurus (3) | |
