Which stage comes earlier in the life history of silk moth-pupa or larva ?

Answer

To determine which stage comes earlier in the life history of the silk moth, we need to analyze the life cycle of the silk moth step by step.

### Step-by-Step Solution:

1. **Understanding the Life Cycle**: The life cycle of the silk moth consists of several stages: egg, larva (caterpillar), pupa (cocoon), and adult moth.

2. **Identifying the First Stage**: The first stage in the life cycle is the egg. After a few days, the egg hatches into the next stage.

3. **Larva Stage**: The second stage is the larva, which is also known as the caterpillar. This stage follows the egg stage and is characterized by the larva feeding on mulberry leaves.

4. **Pupa Stage**: After the larva stage, the silk moth enters the pupa stage, where it forms a cocoon and undergoes transformation.

5. **Conclusion**: Since the larva stage comes after the egg stage and before the pupa stage, it is clear that the larva stage comes earlier than the pupa stage.

### Final Answer:
The larva stage comes earlier in the life history of the silk moth than the pupa stage.
