Aquatic insects or water insects live some portion of their life cycle in the water. They feed in the same ways as other insects . Some diving insects, such as predatory diving beetles , can hunt for food underwater where land-living insects cannot compete .
Insects as food or edible insects are insect species used for human consumption. [1] Over 2 billion people are estimated to eat insects on a daily basis. [ 2 ] Globally, more than 2,000 insect species are considered edible, though far fewer are discussed for industrialized mass production and regionally authorized for use in food.
Eighty percent of the world's nations eat insects of 1,000 to 2,000 species. [10] [11] FAO has registered some 1,900 edible insect species and estimates that there were, in 2005, some two billion insect consumers worldwide. FAO suggests eating insects as a possible solution to environmental degradation caused by livestock production. [12]
Insects are among the most diverse groups of animals on the planet, including more than a million described species and representing more than half of all known living organisms. [ 1 ] [ 2 ] The number of extant species is estimated at between six and ten million, [ 1 ] [ 3 ] found in nearly all environments , although only a small number of ...

[3] Once they hatch, the majority of aquatic macroinvertebrates undergo three main life stages: nymph, pupa, and adult. Some taxa, like dragonflies, spend their adult stage outside the water.
When applied, neonicotinoids are typically sprayed widely and persist on the soil, in the water, and are taken up by plants. They are toxic and enter into the insect's body resulting in the impairment of foraging success, brood and larval development, and memory and learning as well as causing harmful effects on the nervous system, immune ...
The "Spanish fly", Lytta vesicatoria, has been considered to have medicinal, aphrodisiac, and other properties. Human interactions with insects include both a wide variety of uses, whether practical such as for food, textiles, and dyestuffs, or symbolic, as in art, music, and literature, and negative interactions including damage to crops and extensive efforts to control insect pests.
The same tooth arrangement is however also suited for eating animals with exoskeletons, thus the ability to eat insects is an extension of piscivory. [3] At one time, insectivorous mammals were scientifically classified in an order called Insectivora. This order is now abandoned, as not all insectivorous mammals are closely related.
