What’s the Plural of Larva: Understanding Insect Development Stages

  • Larvaeand “larvas” are both accepted plural forms of “larva.”
  • The dual pluralization reflects “larva’s” Latin roots and its integration into English.
  • Usage of “larvae” or “larvas” can depend on the context and preference for traditional or Anglicized forms.

The commonly accepted plural forms of “larva” are both “larvae” and “larvas.” This duality stems from “larva” having Latin origins, where many scientific and biological terms retain their Latin or Greek plural forms. However, the use of the alternative “larvas” acknowledges the naturalization process of loanwords into English, where common English pluralization rules—adding an “s” or “es”—are applied.

What’s the Plural of “Larva”?

The correct plural form of larva can be either larvae or larvas. Here’s a breakdown of each:


Here are examples of the term in use:

  • Many insects, such as butterflies and beetles, spend part of their lifecycle as larvae.
  • The garden was found to be teeming with the larvas of various insects.

What’s the Singular of Larva?

Below are two tables that provide clarity on the term’s usage in both singular and plural forms:

Singular Usage:

Singular FormDefinition
LarvaAn immature, wingless, and often wormlike form of an insect.

Plural Usage:

Plural FormsUsage Notes
LarvaeThe preferred plural form, derived from Latin.
LarvasAn accepted yet less common plural form.

When discussing this stage, it’s pivotal to use the correct grammatical number:

  • Singular Example: A caterpillar is the larva of a butterfly.
  • Plural Example: The garden was full of larvae, signaling a healthy ecosystem.

Defining the Word “Larva”

In the study of entomology, the term “larva” designates a distinct developmental stage of an organism. To be more specific:

  • Larva refers to the immature form of an insect.
  • It is the stage following the egg in the life cycle.
  • This form often looks very different from the adult stage, and typically, it is a feeding stage that primarily focuses on growth.

Entomologists use the term larva when discussing insects with complete metamorphosis, which, aside from larval and adult stages, also includes pupal stages.

Examples of organisms with this lifecycle include butterflies and moths, known as Lepidoptera, as well as various species of beetles and bees. The characteristics of larvae can vastly differ even within the same species, based largely on their environment and developmental stages.

Here are key points regarding the word “larva”:

OriginLatin word meaning “ghost” or “mask”.
MeaningOften refers to a wormlike form of an insect preparing to undergo transformation.
SignificanceRepresents a stage where metamorphosis into a different physical form occurs.

When referring to more than one larva, different plural forms are acceptable:


Other Latin Nouns

First Declension
Latin nouns from the first declension typically have a singular form ending in ‘-a’ and form their plurals by changing this ending to ‘-ae’. These are primarily feminine nouns.


Second Declension
Nouns from the second declension, often masculine or neuter, can have singular endings in ‘-us’ or ‘-um’, changing to ‘-i’ or ‘-a’ in the plural respectively.

  • Masculine Examples:

    • Singular: alumnus, focus
    • Plural: alumni, foci
  • Neuter Examples:

    • Singular: bacterium, datum
    • Plural: bacteria, data

Third Declension
This declension has a variety of endings in Latin, with English often retaining the Latin plural.

  • Singular: corpus, genus
  • Plural: corpora, genera

Fourth Declension
Perhaps less common, the fourth-declension nouns end in ‘-us’ and the plural form typically ends in ‘-us’, a rare instance where the singular and plural forms are identical.

  • Example:
    • Singular: manus (hand)
    • Plural: manus (hands)

Origin of the Word “Larva”

LatinLarvaGhost, Mask

The use of “larva” in describing the juvenile form of an animal, particularly insects, emerged due to the dramatic transformation these creatures undergo—much like the changing disguises of ghosts or spirits in folklore.

  • Juvenile Form: Refers to the early life stage of an organism
  • Metamorphosis: Process of transformation from larva to adult

As the science of entomology evolved, “larva” became the standard term for the early, often worm-like stage of insects that undergo metamorphosis. Such larvae are generally quite distinct from their adult forms, lacking wings and often bearing different structures and behavior.

LarvaWingless, often worm-like
PupaIntermediate stage before adulthood
AdultFully formed, capable of reproduction
