The eggs of amphibians are typically laid in water and hatch into free-living larvae that complete their development in water and later transform into either aquatic or terrestrial adults.

Frog larvae are known as tadpoles and typically have oval bodies and long, vertically flattened tails with fins.

The larvae of the more ancestral Hymenoptera resemble caterpillars in appearance, and like them, typically feed on leaves.

For instance, Wyeomyia larvae typically get frozen into solid lumps of ice during winter and only complete their development in spring.

Regardless of the depth where eggs and larvae reside, they are typically pelagic.

The short-beaked echidna's diet consists largely of ants and termites, while the Zaglossus species typically eats worms and insect larvae.

Nauplii are typically initially brooded by the parent, and released after the first moult as larvae that swim freely using setae.

All 8 species are nocturnal carnivores which hunt a range of small creatures, typically insects, larvae, insect eggs, small lizards and the young of small mammals.

The larvae typically settle on their preferred substrates in May, and then the colony undergoes growth, stasis and reproduction, shrinkage, and senescence around September, except in regions where temperature allows them to persist further into the winter.

The larvae are wood-borers, typically living in fungus-infested wood, and sometimes found in wood construction.

They are typically abundant in streams in their range, both adults and larvae living amongst and feeding on the filamentous algae that grows on rocks, especially those in the marginal shallows.

Among the non-parasitic and non-social Aculeata, larvae are fed with captured prey ( typically alive and paralyzed ) or may be fed pollen and nectar.

When attacked, the larvae will expose the osmeterium, a y-shaped organ typically folded up within the caterpillar.

The larvae of the Sesiidae typically bore in wood or burrow in plant roots.

Although its members occur in arid and sandy areas worldwide ( except Australia ), only the nocturnal adults have ever been collected ( typically at lights ), and both the larvae and biology of Glaresis are as yet unknown.

When ready to pupate, the larvae typically cut an exit hole, then return to their feeding chamber.

However, larvae of some species – typically Ceratocampinae, like the Regal Moth ( Citheronia regalis ) and the Imperial Moth ( Eacles imperialis ) – burrow and pupate in a small chamber beneath the soil.

Following ingestion of the copepod by a suitable second intermediate host, typically a minnow or other small freshwater fish, the procercoid larvae are released from the crustacean and migrate into the fish's flesh where they develop into a plerocercoid larvae ( sparganum ).

The composition of any particular schmutzdecke varies, but will typically consist of a gelatinous biofilm matrix of bacteria, fungi, protozoa, rotifera and a range of aquatic insect larvae.

Free-living veliger larvae typically feed on phytoplankton ; however, the larvae of some species are lecithotrophic ( nourished by yolk from the egg that is retained within their bodies ) and do not need to feed.

The larvae are carnivorous, typically consuming aquatic invertebrates.

The larvae typically feed on only one family of trees, but closely related species will feed on distantly related plants ; for example different members of the genus Datana feed on Juglandaceae, Hamamelidaceae, Ericaceae and Anacardiaceae ( Miller 1992 ).

The development of the Andrena larvae is very rapid, so that by the end of spring they have already pupated and become adults.

Most amphibians lay their eggs in water and have aquatic larvae that undergo metamorphosis to become terrestrial adults.

These larvae do not have gills but instead have specialised areas of skin through which respiration takes place.

Pond-type larvae often have a pair of balancers, rod-like structures on either side of the head which perhaps prevent the gills from getting clogged up with bottom sediment.

Some members of the genera Ambystoma and Dicamptodon have larvae that never fully develop into the adult form but this varies with species and with populations.

In some species the larvae have large yolks, go to feed, and quickly settle on a surface.

Others produce larvae that have little yolk but swim and feed for a few days before settling.

Tunicate larvae have both a notochord and a nerve cord which are lost in adulthood.

The ammonoids utilized a planktonic strategy of reproduction ( numerous eggs and planktonic larvae ), which would have been devastated by the K – Pg extinction event.

Such larvae have soft bodies with no limbs.

The prolegs do not have crochet hooks at the ends unlike the larvae of the Lepidoptera.

Also, the larvae of all Apocrita do not have legs, prolegs, or ocelli.

These two groups have long been considered close relatives because of the common presence of trochophore larvae, but the annelids were considered closer to the arthropods because they are both segmented.

The larvae, and the adults of some highly aquatic species, also have a lateral line organ, similar to that of fish, which can detect changes in water pressure.

The others have the characteristic wide flat beak adapted to dredging-type jobs such as pulling up waterweed, pulling worms and small molluscs out of mud, searching for insect larvae, and bulk jobs such as dredging out, holding, turning headfirst, and swallowing a squirming frog.

The eggs hatch into aquatic larvae, called tadpoles, that have internal gills and tails.

Lungfish larvae also have external gills, as does the primitive ray-finned fish Polypterus, though the latter has a structure different than amphibians.

Studies done on the potential of the embryo at different stages have shown that at both the two and four cell stage of development P. flava blastomeres can go on to give rise to a tornaria larvae, so fates of these embryonic cells don ’ t seem to be established till after this stage.

The larvae have rings of cuticular hooks and terminal stylets that are believed to be used to enter the hosts.

While the larvae of the cheese fly are killed by the digestive process, certain species of fly larvae ( which belong to a completely different family ) have adapted to pass through the mammalian digestive system alive when accidentally ingested ( stomach acids do not usually kill them ).

These larvae have legs ( which lack a trochanter, the leg segment that forms the articulation between the basal coxa and the femur ), and actively search out new hosts.
