Acroneuriinae is a of stoneflies within the Perlidae, comprising approximately 32 and 520 described . Members are aquatic insects whose larvae inhabit freshwater environments. The subfamily has been the subject of recent mitogenomic research, including the first documented gene rearrangements in the order Plecoptera.

Identification
Acroneuriinae larvae can be distinguished from other Perlidae by combinations of gill arrangements, cercal segment counts, and capsule , though specific diagnostic characters vary among constituent . typically possess two ocelli and reduced or modified thoracic compared to some related groups.

Habitat
Cold, clean, well-oxygenated freshwater including streams and rivers. Larvae are strictly aquatic and require high water quality.
Distribution
Temperate and tropical regions with documented records from North America and Asia, including specimens from Tianmu Mountain (Zhejiang Province, China) and the Cucharas River (Colorado, USA).
Diet
and ; larvae feed on other aquatic and organic matter.
Life Cycle
Hemimetabolous development with aquatic larval stages and terrestrial . Specific instar counts and developmental durations vary among .
Behavior
Larvae serve as sensitive bioindicators of health due to their intolerance of pollution and degradation. are generally short-lived and primarily focused on .
Ecological Role
Contribute to nutrient cycling and energy flow in freshwater as both and prey within aquatic .
Human Relevance
Used in biomonitoring programs to assess water quality and health in freshwater systems.
Similar Taxa
- PerlinaeAnother of Perlidae; differs in gill and geographic distribution patterns, with Perlinae more broadly distributed in the Palearctic.
- Perlodinae of related Perlodidae; distinguished by differences in wing venation and larval gill structure.

Mitogenomic Research
The first gene rearrangements in the order Plecoptera were documented in Acroneuriinae (Hemacroneuria ovalis and Hesperoperla pacifica). The ND6 gene exhibits faster evolutionary rates than COI, with all 13 protein-coding genes under purifying selection.
Phylogenetic Status
Phylogenetic analyses support monophyly of tribes Claasseniini, Neoperlini, and Kiotinini within Acroneuriinae, but not monophyly of Acroneuriini or Perlini.
