larva
Let an agent handle larvae by taxon, stage, identification, ecology and practical contexts such as gardening, fisheries and pest control.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent handle larvae by taxon, stage, identification, ecology and practical contexts such as gardening, fisheries and pest control.
A distinct juvenile form of many animals, such as insects, amphibians, fish and marine invertebrates, that hatches from the egg and later transforms into the adult by metamorphosis; examples include caterpillars, maggots, grubs and tadpoles.
What it is for: Biology, ecology, agriculture and aquaculture.
It can be identify larvae to a group; describe larval stages and metamorphosis; understand larval roles in ecosystems; find pest management guidance.
Distinguishing features
Juvenile stage
Often very different from the adult
Ends in metamorphosis
Frequently the main feeding stage
What it looks like
Often worm-like or quite unlike the adult, such as caterpillars, grubs, tadpoles and planktonic forms.
How it is recognised
Caterpillars, maggots and grubs
Tadpoles with tails and gills
Nymphs of some insects resemble adults more closely
