Nymphs of aquatic insects, as in the Odonata, Ephemeroptera, and Plecoptera orders, are also called naiads, an Ancient Greek name for mythological water nymphs. Some entomologists have said that the terms larva, nymph and naiad [ 4 ] should be used according to the developmental mode classification (hemimetabolous, paurometabolous or ...
Belostomatidae is a family of freshwater hemipteran insects known as giant water bugs or colloquially as toe-biters, Indian toe-biters, electric-light bugs (because they fly to lights in large numbers), alligator ticks, or alligator fleas (in Florida). They are the largest insects in the order Hemiptera. [1]

The Gerridae are a family of insects in the order Hemiptera, commonly known as water striders, water skeeters, water scooters, water bugs, pond skaters, water skippers, water gliders, water skimmers or puddle flies.
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.
The pondskaters or water striders (Gerridae) are also associated with water, but use the surface tension of standing water to keep them above the surface; [44] they include the sea skaters in the genus Halobates, the only truly marine group of insects.

The nymphs of the hemimetabolous orders mayflies, dragonflies and stoneflies, and the larvae of the holometabolous orders megalopterans and caddisflies, possess tracheal gills, which are outgrowths of the body wall containing a dense network of tracheae covered by a thin cuticle through which oxygen in the water can diffuse.

Some true water bugs (Nepomorpha) may also be fully aquatic for their entire lives, but can leave the water to travel. The nymphs (technically, "naiads") are aquatic and live in the benthic zone of well-oxygenated lakes and streams. A few species found in New Zealand and nearby islands have terrestrial nymphs, but even these inhabit only very ...
The nymphs are highly susceptible to pollution and can be useful in the biomonitoring of water bodies. [4] Once they have emerged, large numbers are preyed on by birds, bats and by other insects, such as Rhamphomyia longicauda. [5] Mayfly nymphs may serve as hosts for parasites such as nematodes and trematodes. Some of these affect the nymphs ...
