Is there a caterpillar or pupa stage?

Answer

### Step-by-Step Solution:

1. **Understanding the Life Cycle**:
- The life cycle of insects, particularly butterflies, includes several stages: egg, larva (caterpillar), pupa, and adult.

2. **Identifying the Caterpillar Stage**:
- The caterpillar is the larval stage of the insect. After the egg hatches, it develops into a larva, which is commonly referred to as a caterpillar.

3. **Growth of the Caterpillar**:
- During the caterpillar stage, the larva grows rapidly, feeding and increasing in size until it reaches full growth.

4. **Transition to Pupa Stage**:
- Once the caterpillar is fully grown, it stops eating and prepares to transition into the next stage, which is the pupa stage.

5. **Understanding the Pupa Stage**:
- The pupa stage, also known as chrysalis in butterflies, is a transitional phase between the larva and the adult. During this stage, significant development occurs as the insect transforms into its adult form.

6. **Emergence of the Adult**:
- After the pupa stage, the adult insect emerges, fully formed and often with wings, completing the life cycle.

### Final Answer:
Yes, there is a caterpillar stage (larva) and a pupa stage in the life cycle of insects such as butterflies.
