What are the stages of incomplete metamorphosis in grasshoppers?

Grasshoppers undergo hemimetabolous (incomplete) metamorphosis, which consists of three primary stages: egg, nymph, and adult.12

• Egg: Typically deposited on the ground or on vegetation, the life cycle begins here. Upon hatching, the young insect may initially emerge as an active embryo enclosed in a thin membrane, referred to as a vermiform larva, before shedding this membrane at an intermediate molt.1
• Nymph: This is the sexually immature stage. Nymphs resemble adults in form and eating habits but are smaller and lack fully developed reproductive organs and wings. During this stage, the insect undergoes a series of molts—typically 4 to 9—with the nymphal body proportions gradually becoming more like those of an adult. There is no pupal or resting stage in this process.312
• Adult: The final stage is reached after the last molt, resulting in a fully developed, winged insect with functional reproductive organs.142
