Definition
Adjective: 1. Describing a type of insect development: Pertaining to or undergoing hemimetamorphosis; specifically, describing insects whose young (nymphs) are aquatic and undergo incomplete metamorphosis, meaning the immature form does not closely resemble the adult form. This is a specialized term in entomology.
Usage and Examples
- As a descriptive adjective:
- Mayflies are classic examples of hemimetamorphic insects.
- The hemimetamorphic life cycle includes egg, nymph, and adult stages, but no pupal stage.
- Scientists studied the gill development in the hemimetamorphic nymphs.
Advanced Usage Notes
