Definition
- Adjective:
- Relating to incomplete metamorphosis in insects: Describes a type of insect development where the young (nymphs) undergo a series of molts, gradually becoming more like the adult form, without a distinct, sedentary pupal stage. The young do not resemble the adult in early stages.
- Pertaining to hemimetabolism: Of or relating to the biological process of hemimetabolism.
Usage Examples
- Adjective:
- Dragonflies and grasshoppers are classic examples of hemimetabolic insects.
- The hemimetabolic life cycle includes egg, nymph, and adult stages.
- In hemimetabolic development, the nymph often lives in a different habitat than the adult.
Advanced Usage
- Scientific Context: The term is primarily used in entomology (the study of insects) and developmental biology to classify and describe insect life cycles. It is often contrasted with "holometabolic" (complete metamorphosis).
- The study compared the growth patterns of hemimetabolic and holometabolic species.
Variants and Related Words
- Hemimetabolism (noun): The process or condition of undergoing incomplete metamorphosis.
- Hemimetabolism is characterized by the absence of a pupal stage.
- Hemimetabolous (adjective): A synonym for "hemimetabolic."
- Mayflies are hemimetabolous insects.
- Hemimetaboly (noun): Another term for hemimetabolism.
Synonyms
- Incompletely metamorphosing: Describing the same developmental process.
- Hemimetabolous: A direct synonym with identical meaning.
- Paurometabolous: A similar term sometimes used interchangeably, though it may imply the nymph and adult share more similar habitats.
Antonyms
- Holometabolic: Describing insects that undergo complete metamorphosis (egg, larva, pupa, adult), where the larval form does not resemble the adult.
- Butterflies are holometabolic, while true bugs are hemimetabolic.
Adjective
- (of an insect with aquatic young) undergoing incomplete metamorphosis in which the young does not resemble the adult
