Aquatic insects live mostly in freshwater habitats, and there are very few marine insect species. [9] The only true examples of pelagic insects are the sea skaters, which belongs to the order Hemiptera, and there are a few types of insects that live in the intertidal zone, including larvae of caddisflies from the family Chathamiidae, [10], the ...
Aquatic macroinvertebrates are insects in their nymph and larval stages, snails, worms, crayfish, and clams that spend at least part of their lives in water. These insects play a large role in freshwater ecosystems by recycling nutrients as well as providing food to higher trophic levels.

They are generally small, long-legged insects and the body length of most species is between 2 and 12 mm (0.08–0.47 in). A few are between 12 and 25 mm (0.47–0.98 in). [ 5 ] Among widespread genera, the North Hemisphere Aquarius includes the largest species, generally exceeding 12 mm (0.47 in), at least among females, and the largest ...
Caddisflies was the only group of these insects to use silk as part of their lifestyle, which has been a contributing factor to their success and why they are the most species-rich order of aquatic insects. [8] About 14,500 species of caddisfly in 45 families have been recognised worldwide, [9] but many more species remain to be described.
For example, the female Tisza mayfly, the largest European species with a length of 12 cm (4.7 in), flies up to 3 kilometres (2 mi) upstream before depositing eggs on the water surface. These sink to the bottom and hatch after 45 days, the nymphs burrowing their way into the sediment where they spend two or three years before hatching into ...
Nepidae is a family of exclusively aquatic Heteropteran insects in the order Hemiptera. [1] They are commonly called water scorpions for their superficial resemblance to scorpions, due to their raptorial forelegs and the presence of a long slender process at the posterior end of the abdomen, resembling a tail. [2]
Corixidae is a family of aquatic insects in the order Hemiptera.They are found worldwide in virtually any freshwater habitat and a few species live in saline water. [1] There are about 500 known species worldwide, in 55 genera, including the genus Sigara.
