In which of the following arthropods the development is paurometabolous? The young hatches from eggs resemble the adult and often occupy the same habitat and they grow by moulting

Options

A. Bombyx
B. Apis
C. Anopheles
D. Periplaneta

Explanation

To solve the question regarding which arthropods exhibit paurometabolous development, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Metamorphosis**:
- Metamorphosis is a biological process involving significant changes in the body structure of an organism as it develops from an immature form to an adult form.
- There are two main types: complete metamorphosis (holometabolism) and incomplete metamorphosis (paurometabolism).

2. **Defining Paurometabolous Development**:
- Paurometabolous development is characterized by the young (nymphs) resembling the adult form.
- There is no pupal stage; instead, the young grow through a series of molts.
- The nymphs often occupy the same habitat as the adults and may have similar feeding habits.

3. **Identifying the Options**:
- The question lists several arthropods: silkworm (Bombyx), honey bee (Apis), mosquito (Anopheles), and cockroach (Periplaneta).
- We need to determine which of these undergoes paurometabolous development.

4. **Analyzing Each Option**:
- **Silkworm (Bombyx)**: Undergoes complete metamorphosis (egg → larva → pupa → adult).
- **Honey Bee (Apis)**: Also undergoes complete metamorphosis (egg → larva → pupa → adult).
- **Mosquito (Anopheles)**: Undergoes complete metamorphosis (egg → larva → pupa → adult).
- **Cockroach (Periplaneta)**: Undergoes paurometabolous development (egg → nymph → adult).

5. **Conclusion**:
- The only arthropod from the options provided that exhibits paurometabolous development is the **cockroach (Periplaneta)**.

### Final Answer:
The arthropod that exhibits paurometabolous development is **cockroach (Periplaneta)**.
