hemimetaboly
Học thuậtThân thiện
Definition
Noun: - Incomplete or partial metamorphosis in insects: A type of insect development characterized by three distinct life stages (egg, nymph, adult) where the nymph resembles a smaller, wingless version of the adult and undergoes a series of molts without a pupal stage.
Usage
- Scientific/Entomological Context: The term is used specifically in entomology to describe and classify insect life cycles.
- Example: "The grasshopper's life cycle is an example of hemimetaboly, as the young nymphs look similar to the adults but lack wings."
Advanced Usage
- Adjectival Form: The process or characteristic is often described using the adjective hemimetabolous.
- Example: "Dragonflies are hemimetabolous insects."
- Contrast with Other Metamorphosis: Used in contrast to holometaboly (complete metamorphosis) and ametaboly (little or no metamorphosis).
- Example: "Entomologists distinguish between hemimetaboly and holometaboly based on the presence or absence of a pupal stage."
