Omnivorous species feed on both the decomposing remains as well as other carrion associated insects, usually necrophagous species. [2] [3] Large numbers of omnivorous insects can slow the rate at which carcass materials are removed by depleting the number of necrophagous larvae. [8]
The main exception is in those species whose larvae are not fully sclerotized, mainly some holometabola; but even most unsclerotized or weakly sclerotized larvae tend to have well-sclerotized head capsules, for example, the larvae of Coleoptera and Hymenoptera. The larvae of Cyclorrhapha however, tend to have hardly any head capsule at all.
The larvae of many lepidopteran species will either make a spun casing of silk called a cocoon and pupate inside it, or will pupate in a cell under the ground. In many butterflies, the pupa is suspended from a cremaster and is called a chrysalis. The adult body has a hardened exoskeleton, except for the abdomen which is less sclerotised. The ...
The fly larvae digest part of the carcass, and the beetle larvae will consume the parts that the fly larvae did not, which typically consists of flesh left on the bones and on the moist inside of the face. [5] Eventually the larvae will fall to the ground, dig into the dirt, and pupate. Adults practice overwintering. [2] [3]
Necrophages are useful for other purposes too. In healthcare, green bottle fly larvae are sometimes used to remove necrotic (dead) tissue from non-healing wounds, [10] [11] and in waste management, black soldier fly larvae are used to convert decomposing organic waste into animal feed.
An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...

The first three stages—egg, larva, and pupa—are largely aquatic, [4] the eggs usually being laid in stagnant water. [5] They hatch to become larvae, which feed, grow, and molt until they change into pupae. The adult mosquito emerges from the mature pupa as it floats at the water surface.
