Stenelmis lignicola
Schmude & Brown in Schmude, Barr & Brown, 1992
riffle beetle
Stenelmis lignicola is a of in the , described in 1992. The specific epithet "lignicola" derives from Latin roots meaning "wood-dweller," suggesting an association with woody substrates. As a member of the riffle beetle family, it is adapted to aquatic or semi-aquatic environments with flowing water. The species is known from North America.

Habitat
() are strongly associated with lotic environments—streams and rivers with current—particularly in riffle zones where water flows over rocky or gravel substrates. The epithet suggests possible association with submerged or waterlogged wood.
Distribution
North America. Specific locality records are sparse; the has been documented in the region but detailed range boundaries remain undefined.
Life Cycle
are aquatic, typically requiring well-oxygenated water. They undergo with , larval, pupal, and stages. Larval development occurs in aquatic environments, with adults often remaining near water.
Behavior
of many Stenelmis are known to crawl on submerged substrates rather than swim actively. They may remain submerged for extended periods, utilizing respiration.
Ecological Role
contribute to in freshwater systems through larval grazing on periphyton and detritus. They serve as bioindicators of water quality due to their sensitivity to oxygen levels and pollution.

Nomenclature
The specific epithet "lignicola" combines Latin "lignum" (wood) with "-cola" (dweller/inhabitant), indicating the describers' recognition of a substrate association. This distinguishes it from with different ecological preferences.
