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.
In fact, in many freshwater aquatic habitats, especially polluted ones, chironomids are often one of the most abundant insects found. Aquatic habitats can be marine or freshwater, the latter including treeholes , bromeliads , interstitial and benthic zones, as well as man-made sewage and artificial containers. [ 20 ]
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.
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 ...
They prey on other water mites, small crustaceans (e.g. cladocerans, ostracods and copepods), the eggs, larvae and pupae of aquatic insects, and non-arthropod invertebrates such as rotifers, nematodes, and oligochaetes. The egg-eating water mites often prey on the eggs of the same insects they parasitise as larvae.
Herbivorous beetles eat only aquatic vegetation, such as algae or leaves. They might also suck juices out the stem of a plant nearby. Scavenger beetles will feed on decomposing organic material that has been deposited. The scavenged material can come from aquatic vegetation, feces, or other small organisms that have died. [5]
