• Analetris

  Analetris is a genus of sand-dwelling mayflies in the family Acanthametropodidae, established by Edmunds in 1972. The genus contains at least two species: the extant Analetris eximia and the extinct †Analetris secundus. Members of this genus are specialized inhabitants of riverine environments with unstable silty substrates. The best-studied species, A. eximia, is considered endangered due to habitat destruction from reservoir construction.

• Heterocloeon curiosum

  curious small minnow mayfly

  Heterocloeon curiosum is a small minnow mayfly in the family Baetidae, native to North America. It has been studied in Virginia river systems, where it demonstrates bivoltine life history with two summer generations. Reservoir construction with surface release can significantly alter its emergence timing, larval density, and fecundity through thermal regime changes.
