Classification of aquatic insects
What are aquatic insects called?
Ephemeroptera – mayflies. Odonata – dragonflies and damselflies. Plecoptera – stoneflies. Megaloptera – alderflies, fishflies, and dobsonflies. Neuroptera – lacewings.
How many aquatic insects are there?
More than 60% of the freshwater species diversity is represented by aquatic insects, with approximately 130,000 described extant species [2–4]. They spend one or more stages of their life cycle in aquatic habitats, with the majority moving to terrestrial areas as adults.
What are the classifications of an insect?
Insects can be divided into two groups historically treated as subclasses: wingless insects, known as Apterygota, and winged insects, known as Pterygota. The Apterygota consist of the primitively wingless order of the silverfish (Zygentoma).
Are there any aquatic insects?
The only truly marine insects living far from the shore is the sea skater or Halobates. But even they do not live in the water. “The sea skater lives on the surface, pretty much like they do on freshwater lakes. They scoot around, feeding on trapped insects and dead organisms.
Why are aquatic insects important?
They are important contributors to energy and nutrient processing, including capturing nutrients and returning them to terrestrial ecosystems and purifying water. They provide recreation to fishermen and nature lovers and are cultural symbols.
Which is the example of aquatic insect found in aquaculture?
Predaceous diving beetles, some nearly 2.5 cm long, are common in weedy ponds, some nearly 2.5 cm long. The whirligig beetles are very common and can often be found swimming together on the surface of calm water in large groups.
Where do aquatic insects live?
the water
Aquatic insects live in the water as larvae most of their lives, then emerge onto land for a brief period as winged adults.
What do aquatic insects eat?
Diet is mostly algae or detritus. Springtails (Collembola) – Feed on detritus, algae, fungi or dead animal matter. Fishflies and Alderflies (Megaloptera) – Aquatic larvae are active predators that feed on aquatic insects, worms, crustaceans, snails and clams.
What insects live in water?
Some insect orders contain only species that are aquatic in some life stages (e.g., mayflies, stoneflies, dragonflies, caddisflies, megalopterans), whereas other orders contain both aquatic and terrestrial species (e.g., beetles, bugs, butterflies, neuropterans, orthopterans, and dipterans).
What insects swim in water?
Toe biters, water boatmen and whirligig beetles are some of the best-known insects that swim underwater.
Are there insects that breathe underwater?
Predaceous diving beetles are an aquatic insect family common in lakes, ponds and streams. Streamlined and equipped with legs adapted to swimming, these beetles dive with a breathing bubble trapped beneath their outer wings.

How are insects adapted to aquatic life?
Insects that live in the water are called aquatic. Aquatic insects have legs adapted for swimming. Some aquatic insects have long legs that are used like oars to help the insect swim. Other insects have very short, fat legs that beat quickly for fast swimming.
How do aquatic insects breathe?
Although many aquatic insects live underwater, they get air straight from the surface through hollow breathing tubes (sometimes called siphons) that work on the same principle as a diver’s snorkel.
Do aquatic insects have gills?
Some of these insects have external gills. This means that their gills are on the outside of their body, just like on this caddisfly larva. The water in the stream flows over their gills so the insects can get oxygen to breathe. LINDSAY GLASNER: However, some aquatic insects have internal gills, like dragonflies.
