What stage of development is nymph?
In biology, a nymph is the immature form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (hemimetabolism) before reaching its adult stage. Unlike a typical larva, a nymph’s overall form already resembles that of the adult, except for a lack of wings (in winged species).
What type of metamorphosis has a nymph stage?
Incomplete Metamorphosis
Incomplete Metamorphosis: Incomplete metamorphosis consists of a nymph, which resembles a miniature adult. Complete Metamorphosis: The exoskeleton of the insect is completely molted during the complete metamorphosis.
What are the four stages of a locust?

What kind of development does a nymph have?

What does a cricket nymph look like as an adult?
