pupae

A scientist carefully observes the pupae attached to a leaf.

Definition
  1. Noun (plural of pupa):
    • Developmental stage in insects: "Pupae" refers to the plural form of "pupa," which is the intermediate stage in the life cycle of insects undergoing complete metamorphosis (e.g., butterflies, beetles, flies). During this stage, the insect is enclosed in a protective casing (a cocoon or chrysalis) and transforms from a larva (caterpillar or grub) into an adult.
Usage Examples
  • (The insects entered the resting stage before becoming butterflies.)
  • (They examined the developing insects inside their casings.)
  • (The intermediate stage of mosquito development is aquatic.)
Advanced Usage

  • "in the pupal stage": referring to the state of being a pupa.

    • The insect remains in the pupal stage for several weeks. (It stays as a pupa before emerging as an adult.)

  • "to emerge from the pupae": the act of an adult insect leaving the pupal casing.

    • The butterflies emerged from their pupae in the morning. (They came out as fully formed adults.)
Variants and Related Words
  • Pupa (n): the singular form; a single insect in this stage.
    • One pupa was found attached to the branch. (A single developing insect.)
  • Pupal (adj): relating to or characteristic of a pupa.
    • The pupal case is hard and protective. (The outer covering of the pupa.)
  • Pupation (n): the process of becoming a pupa.
    • Pupation occurs after the larva stops feeding. (The transition into the pupal stage.)
Synonyms
  • Chrysalides: plural of chrysalis, specifically referring to the pupae of butterflies.
  • Cocoons: protective cases spun by some insects for pupae (though technically the pupa is inside the cocoon).
Related Idioms
  • "to pupate": to undergo transformation into a pupa.
    • The caterpillar will pupate in a safe location. (It will form a pupa.)
Additional Notes
  • Usage in biology: "Pupae" is a technical term used in entomology (the study of insects) and is rarely used in everyday conversation. It is always plural; the singular is "pupa."
  • Distinction: Do not confuse "pupae" with "puppy" (a young dog) or "pupil" (a student or part of the eye).
