Bryelmis idahoensis
Barr, 2011
riffle beetle
Bryelmis idahoensis is a of riffle beetle in the Elmidae, described by Barr in 2011. Riffle beetles are aquatic insects that inhabit fast-flowing streams and rivers. The species is known from North America, with its specific epithet suggesting a connection to Idaho. As with other members of Elmidae, it likely has an aquatic larval stage and a partially aquatic stage, though specific biological details for this species remain undocumented in available sources.

Habitat
Riffle beetles (Elmidae) are typically found in fast-flowing, well-oxygenated freshwater including streams, rivers, and springs. Members of the Bryelmis inhabit similar lotic environments.
Distribution
North America. The specific epithet 'idahoensis' indicates the was described from or is associated with Idaho, though precise collection localities are not detailed in available sources.
Behavior
As with other riffle beetles, likely cling to submerged rocks and debris in fast currents using their modified legs. Adults are generally poor swimmers and rely on crawling along substrates.
Ecological Role
Riffle beetles contribute to nutrient cycling in freshwater through their feeding activities. They serve as indicators of good water quality due to their requirement for well-oxygenated, unpolluted flowing water.
Human Relevance
Riffle beetles including Bryelmis are used as bioindicators of stream health and water quality. They have no known direct economic importance to humans.
Similar Taxa
- Other Bryelmis species share similar aquatic habits and ; identification to level requires examination of specific morphological characters described in Barr 2011.
- Other Elmidae genera (e.g., Elmis, Stenelmis)These share the riffle beetle habit of clinging to rocks in fast currents but differ in body form, leg structure, and other taxonomic characters.

Taxonomic note
Described by Barr in 2011, this is a relatively recently described within a of North American riffle beetles. The specific epithet 'idahoensis' follows the pattern of many western North American species named for their type locality or primary region of occurrence.
