imaginal

A butterfly emerges from its imaginal stage inside a chrysalis.

Definition
  1. Adjective:
    • Relating to an imago: "imaginal" refers to the adult, reproductive stage of an insect (the imago), as distinct from earlier developmental stages like larvae or pupae.
    • Pertaining to the final form: In entomology, it describes characteristics, structures, or processes associated with the fully developed, sexually mature insect.
Usage Examples
  • (The adult insect stage after metamorphosis.)
  • (Embryonic tissues that develop into adult insect structures.)
Advanced Usage
  • "imaginal disc": a group of cells in insect larvae that develop into specific adult structures during metamorphosis.

    • The imaginal discs for the legs and antennae are present in the larval stage. (Precursors to adult features.)
  • "imaginal moult": the final shedding of the exoskeleton that reveals the adult insect.

    • The imaginal moult transforms the pupa into a flying beetle. (The last moult to the adult form.)
