A larva (/ ˈlɑːrvə /; pl.: larvae / ˈlɑːrviː /) 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.
Sep 2, 2024 · larva, stage in the development of many animals, occurring after birth or hatching and before the adult form is reached. These immature, active forms are structurally different from the adults and are adapted to a different environment.

- Eruciform. Does it look like a caterpillar? Eruciform larvae look like caterpillars and in most cases, are caterpillars. The body is cylindrical with a well-developed head capsule and very short antennae.
- Scarabaeiform. Does it look like a grub? Scarabaeiform larvae are commonly called grubs. These larvae will usually be curved or C-shaped, and sometimes hairy, with a well-developed head capsule.
- Campodeiform. Campodeiform larvae are usually predaceous and typically quite active. Their bodies are elongate but slightly flattened, with well-developed legs, antennae, and cerci.
- Elateriform. Does it look like a worm with legs? Elateriform larvae are shaped like worms, but with heavily sclerotized—or hardened—bodies. They have short legs and very reduced body bristles.
Nov 21, 2023 · What is Larva? Humans give birth to babies; chicks hatch out of chicken eggs, and dogs whelp puppies. What do all three of these situations have in common? Each scenario is a young animal that...
- One example of a larva is the caterpillar that will transform into a butterfly. Another example of a larva is the tadpole that will become a frog.
- A "larva" is a single larval animal, meaning an animal must undergo a metamorphic event to become a sexually reproductive adult. "Larvae" is the pl...
- Larvae is the plural form of a single larva. For example, one larva will hatch from one egg, but a group of many eggs results in multiple larvae. S...
- Three stages can identify some animals: a larval stage; this would start as an egg, then a larva, and finally, an adult. However, most larval anima...
- Larvae are juvenile animals that must undergo metamorphosis to become adults. They typically function to allocate resources and grow before transit...
Aug 26, 2019 · In this review, we support the century old theory by Berlese that the larval form arose by ‘de-embryonization’, i.e. through the suppression/arrest of ancestral programmes of embryonic development.

About 75% of all insect species go through the four stages of complete metamorphosis - egg, larva, pupa, and adult. The larva is a specialized feeding stage that looks very different from the adult. Fortunately, there are just a few basic larval types and they are relatively easy to recognize.
Larval evolution provides the key to unlocking metazoan evolution and diversification. Yet, because of larval adaptations (caenogenesis), only some larvae have provided useful information for reconstructing phylogenetic histories and evaluating evolutionary relationships.
