Habitat
Lotic freshwater environments, specifically streams and rivers. Calineuria californica has been documented in Sierra foothill streams with specific studies on nymphal development in these .
Distribution
Western North America (California, Idaho, Alberta, British Columbia) and East Asia (Japan). Distribution records from GBIF indicate presence in: Alberta, British Columbia, California, Idaho, and Japan.
Life Cycle
development with aquatic nymphal stage and terrestrial stage. For C. californica, nymphal development and growth rates have been quantified in Sierra foothill streams, with of adults occurring after stream-dwelling nymphal period.
Ecological Role
Aquatic function as in stream . As , they occupy higher in freshwater .
Human Relevance
Used as bioindicators of stream water quality due to sensitivity to environmental conditions. C. californica has been studied as a model organism for understanding in western North streams.
