A larva (/ ˈ l ɑːr v ə /; pl.: larvae / ˈ l ɑːr v iː /) is a distinct juvenile form many animals undergo before metamorphosis into their next life stage. Animals with indirect development such as insects , some arachnids , amphibians , or cnidarians typically have a larval phase of their life cycle .
The larvae develop into pupae and then into adults. Adults live only long enough to reproduce and they may form large mating swarms, often around dusk. The life cycle generally takes 4-5 weeks. [1] The larvae of most gall gnats (Cecidomyiidae), such as the Hessian fly larva, form galls in flowers, leaves, stems, roots or other plant parts. [8]
Many of these larvae retract their heads into their thorax. [34] [64] The spiracles in the larva and pupa do not have any internal mechanical closing device.

Maggots feeding on an opossum carrion Maggots on a porcupine carcass Maggots from a rabbit. Common wild pig (boar) corpse decomposition timelapse. Maggots are visible. A maggot is the larva of a fly (order Diptera); it is applied in particular to the larvae of Brachycera flies, such as houseflies, cheese flies, and blowflies, [1] rather than larvae of the Nematocera, such as mosquitoes and ...
Lepidopteran caterpillars can be differentiated from sawfly larvae by: the numbers of pairs of pro-legs; sawfly larvae have 6 or more pairs while caterpillars have a maximum of 5 pairs. the number of stemmata (simple eyes); the sawfly larvae have only two, [7] while caterpillars usually have twelve (six each side of the head).
A cocoon is a casing spun of silk by many moths and caterpillars, [16] and numerous other holometabolous insect larvae as a protective covering for the pupa. Cocoons may be tough or soft, opaque or translucent, solid or meshlike, of various colors, or composed of multiple layers, depending on the type of insect larva producing it.

A dragonfly in its radical final moult, metamorphosing from an aquatic nymph to a winged adult.. In biology, moulting (British English), or molting (American English), also known as sloughing, shedding, or in many invertebrates, ecdysis, is a process by which an animal casts off parts of its body to serve some beneficial purpose, either at specific times of the year, or at specific points in ...
