AQUATIC AND SEMIAQUATIC HETEROPTERA OF ALBERTA, SASKATCHEWAN, AND MANITOBA (HEMIPTERA)
Memoirs of the Entomological Society of Canada, 1967AbstractNinety-five species of aquatic and semiaquatic Heteroptera are recorded from the Prairie Provinces of Canada, representing the following families: Belostomatidae 3, Corixidae 41, Gelastocoridae 1, Gerridae 8, Hebridae 2, Hydrometridae 1, Mesoveliidae 1, Nepidae 2, Notonectidae 6, Pleidae 1, Saldidae 26, and Veliidae 3. Also included are data on

CLYPEAL MODIFICATION IN SOME LITTORAL AND AQUATIC HETEROPTERA
Canadian Journal of Zoology, 1965In representatives of the littoral heteropteran families Ochteridae and Gelastocoridae and the aquatic families Corixidae, Notonectidae, and Naucoridae, the anteclypeus is greatly expanded laterally. In all but the Corixidae these expansions have fused with the loral plates, concealing all or part of the lorogenal clefts and much of the maxillary ...

Distribution and associations of the aquatic Heteroptera of the Balearic Islands (Spain)
Hydrobiologia, 1996Twenty-five species of aquatic Heteroptera were collected from the Balearic Islands. Five are first records (Sigara nigrolineata, Micronecta scholtzi, Ranatra linearis, Notonecta meridionalis and Hebrus pusillus). Previous records are also discussed.

Journal of Applied Ecology, 1969
Woodwalton Fen is an important National Nature Reserve, a short account of which was given by Duffey (1956). In order to maintain the wet conditions characteristic of fenland, water must be obtained from outside the reserve and distributed within it.

NEW RECORS OF AQUATIC AND SEMI-AQUATIC BUGS (HETEROPTERA: NEPOMORPHA, GERROMORPHA) FROM MONGOLIA
Transactions of Papanin Institute for Biology of Inland Waters RAS, 2023New distributional records for 17 species of aquatic and semi-aquatic bugs are provided from Mongolia: two species recorded for the first time for the country, Corixidae: Sigara (Sigara) striata (Linnaeus, 1758) and Gerridae: Aquarius paludum paludum (Fabricius, 1794).

The Effect of Dredging of a Small Lowland River on Aquatic Heteroptera
Annales Zoologici Fennici, 2016Rehabilitation of river beds is sometimes necessary, particularly when a substantial amount of bottom sediment causes unnaturally slow water flow. However, it is difficult to predict whether such procedures will negatively affect biodiversity and species composition of organisms inhabiting these sites.

ON THE RESPIRATION OF AQUATIC HEMIPTERA HETEROPTERA WITH SPECIAL REFERENCE TO THE CORIXIDAE
Proceedings of the Zoological Society of London, 1960Aquatic Hemiptera Heteroptera have ventrally placed anterior thoracie and abdominal spiracles, the posterior thoracic and first abdominal spiracles being situated dorsally. Internally the spiracles are joined by paired thoracic and abdominal longitudinal tracheal trunks. Gas bubbles carried on the body surface function as gas stores and physical gills.

Attachment forces of the hemelytra-locking mechanisms in aquatic bugs (Heteroptera: Belostomatidae)
Journal of Insect Physiology, 2003Combined hemelytra-locking system of Heteroptera, consisting of several locking mechanisms, aids the mechanical stabilisation of the body at rest, resists external loads, and keeps air stored with the option to easily unlock hemelytra prior to flight. The resistance to unlocking of the hemelytron was measured (in mN) with the aid of a load cell force ...

Aquatic Hemiptera (Heteroptera) of Kazakhstan, with notes on life history, ecology and distribution
Zootaxa, 2015Based on extensive field collections (2000-2014) in Kazakhstan and a review of the material in the National Institute of Zoology of Kazakhstan, we identified 68 species of aquatic Hemiptera from 11 families. Most species have broad zoogeographic distribution, dominated by West Eurasian fauna (18 species) and West Palearctic fauna (10 species).
