The Individual

We focused on the relative number of flying adult caddisflies on the river surface captured by sticky board traps with the aim of elucidating differences in the distribution pattern of caddisfly larvae along the slope in the middle reaches of the Shinano River. The individual number of adult caddisflies caught increased from April and decreased from October. Even in the same middle reaches of a river, there was a large difference geographically in the species captured. Hydroptila sp. was caught mainly downstream of the Taishyobashi Bridge, Psychomyia acutipennis (Ulmer 1908) in the vicinity of the Taishyobashi Bridge, and Stenopsyche marmorata Navás 1920 upstream of the Awasabashi Bridge. It is known that the slope of the Shinano River bed suddenly becomes less and the flow rate slower in the area from the Taishyobashi Bridge to the Awasabashi Bridge, and it was shown that the species composition and number of aquatic insects caught changes with the change in the slope of the river bed.

Three investigations into species composition in aquatic insects in Ngoc Linh Special-use Forest in Quang Nam (March, September, 2015 and March, 2016). At 15 sampling sites in selected waterbodies, aquatic insects were sampled quantitatively by Surber net and qualitatively by hand net. The study has showed a total of 86 species, belonging to 69 genera, 40 families, 8 orders of aquatic insects: 24 Odonata species, 21 Ephemeroptera species, 13 Tricoptera species, 11 Hemiptera species, 7 Plecoptera species, 6 Coleoptera species, 3 Diptera spieces and 1 Megaloptera species. The three orders, Odonata, Ephemeroptera, Tricoptera, predominated (67,45%) the aquatic insect fauna in terms of species richness. This study has provided the data of aquatic insects in this area

Aquatic Insect Fauna

Aquatic macroinvertebrate diversity and composition in streams along an altitudinal gradient in Southeastern Brazil. A study concerning taxonomic richness and composition of the aquatic insect fauna in streams within the same catchment basin along an altitudinal gradient in Southeast Brazil, was conducted to test the hypothesis that there is a faunal discontinuity in the biocenotic composition, related to differences in altitude and latitude. In Southeastern Brazil, around latitude 22°, this faunal transition from rhithron to potamon biocenosis should occur at 500 m above sea level. Eighteen tributaries of the Mambucaba River, at Serra da Bocaina National Park, SP-RJ, Brazil, were studied. The streams were separated into 6 altitudinal zones (zone 1: above 1500 m; zone 2: 1200-1300 m; zone 3: 900-1000 m; zone 4: 400-700 m; zone 5: 100-300 m; and zone 6: 0-100 m) each including three streams. The aquatic insects were identified at the lowest possible taxonomic level. The highest richness was observed in altitudes between 1200-1300 m, while the lowest occurred in altitudes below 100 m. The Indicator Value method indicated taxa characteristic for four of the six altitudinal zones considered in this paper. Sorensen's Index and CCA results showed that distribution and composition of aquatic insect fauna of Serra da Bocaina National Park was influenced primarily by altitude and temperature rather than stream size. The absence of indicator species and the lower abundance in altitudes between 400-700 m suggest a transition from rhithral to potamal fauna, which is distinct at 200 m.

Diversity of aquatic insect fauna of Surha Tal, district Ballia (U.P.) was studied during 2006-08. Twenty nine species of aquatic insect were collected. In class insect four orders namely Coleoptera, Hemiptera, Odonata and Diptera belonging to fourteen families Dytiscidae, Gyrinidae, Hydrophlidae Notonectidae, Palaeidae, Nepidae, Belostomatidae, Hydrometridae, Gerridae. Gomphidae, Libellulidae, Coegrionidae. Chironomidae, Culicidae having twenty genera and twenty nine species were identified.

AbstractIn general, the aquatic insects of freshwater wetlands have been inadequately studied despite their apparent importance in wetland habitats, especially in energy and nutrient transfer. The Biological Survey of Canada (Terrestrial Arthropods) recognized the deficiencies in knowledge of taxonomy and ecology of insect species in wetland habitats and sponsored a "Conference on the aquatic insects of peatlands and marshes" in St. Andrews, New Brunswick, on 3 October, 1984. The Conference summarized current knowledge on the systematics and ecology of aquatic insects of Canadian peatlands and marshes, the wetland habitats chosen for emphasis, and sought to identify needs for research on the structure and dynamics of aquatic insect faunas in these habitats. The proceedings of the Conference are published here. The first two papers provide background information on the habitats under consideration and the interactions among invertebrates and vertebrates in these habitats. A second group of papers considers features of the Hydracarina, Ephemeroptera, Odonata, Hemiptera, Trichoptera, Coleoptera, and Diptera in peatlands and marshes. A final paper summarizes data on the occurrence of aquatic insects in bogs, fens, and marshes, addresses broader questions related to the nature of the insect fauna, and identifies needs for further research. By making accessible systematic and ecological information on aquatic insects of Canadian peatlands and marshes, the proceedings should support and encourage further work in these habitats.
