Healdsburg, CA Posts: 356 | These are common in the Russian River. They're usually found in cutoff pools. The pools have stagnant water with large algal growths and temperatures are higher than the river itself. They're probably Callibaetis pictus since the adults are common at the river right now. | |

Healdsburg, CA Posts: 356 | Probably pretty closely related. Callibaetis belongs in Baetidae while Siphlonurus belongs in Metretopodidae generally a limb below Baetidae on a tree of life. Can be seen in common names as well: Small Minnow Mayflys for Baetidae and Primitive Minnow Mayflys for Siphlonurus. Easiest field ID is Siphlonurus has short antennae (about head length) while Callibaetis has long antennae (about 3 or 4 times length of head). | |

Site Editor Royse City, TXPosts: 1350 | Hi Mark-while Siphlonurus belongs in Metretopodidae I believe Siphlonurus is in family Siphlonuridae, whereas Siphloplecton is in family Metretopodidae. | |
