Which of the following is NOT a stage of insect metamorphosis?

🔑 Key Points
🐣 Stages of Insect Metamorphosis
→ Egg: The first stage of the insect life cycle is the egg, or embryo, for all developmental strategies. The egg begins as a single cell, which develops into the larval form before hatching.
→ Larva: The larval development consists of a series of stages, in which each stage is separated from the next by a molt. It's a complex process involving hormones, proteins, and enzymes. Insects grow in increments. The different larval forms of the various insects are called caterpillars, grubs, maggots, and nymphs.
→ Pupa: This stage of the insect life cycle can be seen in complete metamorphosis. It is an immobile stage of the insect life cycle. During pupation, larval structures break down, and adult structures such as wings appear for the first time.
→ Adult: The adult stage is the final step in the life cycle of insect metamorphosis. When the pupa finishes the transformation and completes its metamorphosis, adults will come out of the pupa.
