Laboratory Manual to accompany Essentials of Biology. Fifth Edition 235 Figure 17.15 Metamorphosis. a. During incomplete metamorphosis of a grasshopper, a series of nymphs leads to a full-grown grasshopper b. During complete metamorphosis of a moth, a series of larvae lead to pupation. The adult hatches out of the pupa. eggs eggs molt moit molt molt Larvae molt molit molt molt pupa Adult Adult Observation: Grasshopper Metamorphosis 1. Use Figure 17.15 to add the grasshopper and the moth to Table 17.4. 2. Examine any specific life cycle displays or plastomounts that illustrate complete and incomplete metamorphosis and add these examples to Table 17.4. Table 17.4 Insect Metamorphosis Specimen Complete or Incomplete Metamorphosis

Explanation / Answer

As we can see in grasshopper the individual stages and not completely different from each other (Nymphs are very similar further even the adult bear similarity) hence it would be classified under Incomplete metamorphosis while the stages of the moths (even the larval stages) are distinct from each other hence it will be classified as complete metamorphosis.

Other examples include

Complete metamorphosis: beetles, butterflies bees

Incomplete metamorphosis: mantises, crickets, and lice
