Baekken, T. 1981. Growth patterns and food habits of Baetis rhodani. Capnia pygmaea atid Diura nanseni in a West Norwegian river. - Holaret. Ecol. 4: 139-144. As a part of weir-pond-eco system project, the growth patterns and food habits of Baetis rhodani (Ephemeroptera), Capnia pygmaea (Plecoptera), atid Diura nanseni (Plecoptera) were itivestigated. S. rhodani was bivoltitie. The winter generation consisted ot three cohorts. C. pygmaea and D. nanseni accomplished their nymphal growth in one… 
The diet of two species of Isoperla (Plecoptera: Perlodidae) in relation to season, site, and sympatry
It is suggested that I. grammatica, which ingests a much wider size range of prey might choose prey of optimal sizes more readily than the more synchronously developing I. difformis, which switched to a temporarily strong utilization of algae in spring.
Feeding of the nymphs of nine stonefly species (Insecta: Plecoptera) from North Africa (Rif Mountains, Morocco) Alimentación de nueve especies de plecópteros (Insecta: Plecoptera) en el Norte de África (Rif, Marruecos)
This study provides the first data on feeding in the genera Hemimelaena and Capnioneura, and finds that over the two size intervals considered, fine organic matter was consumed mainly by the younger nymphs and coarse organic matter by the older ones.
Seasonal sampling indicated that biofilm can provide a valuable food source to E. venosus at times of high flow when detritus is not readily available, and B. rhodani consistently ingested a similar broad diet throughout the year, likely nutrient poor leading to lower growth rates.
Comparative Study of the Nymphal Biology of Two Coexisting Species of Mayflies (Insecta: Ephemeroptera) in a Mediterranean Stream in Southern Europe
It is possible that, because no similar size classes of each species are present at the same time, niche segregation exists between the two species, and this could be the consequence of previous episodes of competition between them.
Geographical and seasonal evidence of cryptic diversity in the Baetis rhodani complex (Ephemeroptera, Baetidae) revealed by means of DNA taxonomy
A DNA-taxonomy phylogenetic analysis of B. rhodani with additional populations coming from Italian and UK sites aims to identify potential cryptic species with a coalescent-based method (GMYC model) and to understand the mechanisms of local coexistence of cryptic species.
Life cycle shifts in Baetis rhodani (Ephemeroptera) in the Norwegian mountains
Although larval growth and voltinism were influenced by water temperature, other factors such as food resources are likely to be important in mountain areas because of the widely distributed mayfly's success in colonising a wide range of running water habitats throughout Europe.
Life cycle and nymphal feeding of Rhabdiopteryx christinae Theischinger 1975 (Plecoptera: Taeniopterygidae)
The study of nymphal gut contents showed that R. christinae acts mainly as collector and scraper (epiphytic and epilitic diatoms), as it is generally accepted for the family Taeniopterygidae.
Studies of aquatic insects in the Atna River 1987–2002
The conclusion is that grazers dominate in the zoobenthos in streams in the treeless alpine region in Norway, as the zoOBenthos community in and below the lake outlet is dominated by collectors (filter feeders).
Trophic ecology of Plecoptera (Insecta): a review
The current knowledge on the trophic ecology of stoneflies is reviewed, including information on the feeding habits of nymphs and adults of the different families and those studies that support particularly interesting findings.


The life histories, trophic relations and production of Stenoperla prasina (Plecoptera) and Deleatidium sp. (Ephemeroptera) in a New Zealand river
The life history, feeding relations and production of the stonefly Stenoperla prasina were studied for 16 months in the Selwyn River, South Island, New Zealand, finding larvae of all sizes were present in all months.
The Food Habits of Stoneflies (Plecoptera) in the Upper Gunnison River, Colorado
Horn's Coefficient of Dietary Overlap showed significance among all predator species for major food categories, but subtle mechanisms such as prey species-and size-selectivity and temporal succession provided sufficient partitioning of the abundant food resources to allow for coexistence.
Effects of Food Quality on Growth of a Stream Detritivore, Paratendipes Albimanus (Meigen) (Diptera: Chironomidae)
Laboratory-determined larval growth rates of the detritivore (collector-gatherer) Par- atendipes albimanus (Chironomidae) responded proportionally to the microbial densities of 4 food sources as well as to the temperature and the interaction of temperature and food quality.
Life cycles and growth rates of Baetis spp. (Ephemeroptera: Baetidae) in the laboratory and in two stony streams in Austria
The growth rates of B. lutheri and B. rhodani were slower in the field than in the laboratory at higher temperatures, and the growing rates of the three Baetis spp.
Food of the New Zealand trichopterans Hydrobiosis parumbripennis McFarlane and Hydropsyche colonica McLachlan
Forage ratios indicated that H. parumbripennis were eating A. tillyardianum at the same relative frequency as their abundance in the fauna, but that the chironomids and Deleatidium sp.
Prey Selection by a Setipalpian Stonefly Nymph, Acroneuria (Calineuria) Californica Banks (Plecoptera:Perildae)
The most important factor determining prey selection appears to be prey availability, and no great preference for any particular prey was apparent.
Benthos and Allochthonous Organic Matter in Streams
Investigations into the vertical distribution of stream animals by means of a coring technique have demonstrated that they could be found many decimeters down in the gravel; a maximum of 17% was
Life histories and drifting of the Plecoptera and Ephemeroptera in a Dartmoor stream
It appears that life histories often differ from place to place and from year to year, and that much of this variation is related to temperature (Macan 1961; Pleskot 1951, 1958, 1961).
Ingestion and growth in Sericostoma personatum (Trichoptera) in relation to the nitrogen content of ingested leaves
Sericostoma personatum Spence was given autumn-shed leaves with differing nitrogen content and the nitrogen content of the detritus may explain the low utilization efficiencies commonly reported for detritivores.
The ingestion and digestion of algae by Chloeon dipterum L. (Ephemeroptera)
Cultures of the hind-gut contents of larvae collected in the field, and of those fed upon algae in the laboratory, showed that cells of several species of algae remained viable in the gut for periods of at least 20 hours, suggesting that such species pass between the mouthparts without being damaged so that in the absence of a cellulase the digestive enzymes of the gut are unable to penetrate the cell walls.
