Butterflies, moth & honey bees & beetle lay eggs of which type
(a) Microlecithal
(b) Mesolecithal
(c) Telolecithal
(d) Centrolecithal

Options

A. Microlecithal
B. Mesolecithal
C. Telolecithal
D. Centrolecithal

Answer

To determine the type of eggs laid by butterflies, moths, honey bees, and beetles, we need to analyze the characteristics of the different types of eggs mentioned in the options.

### Step-by-Step Solution:

1. **Understand the Types of Eggs**:
- **Microlecithal**: These eggs contain a very small amount of yolk. They are typically found in organisms that develop quickly and do not require much nutrient supply from the yolk.
- **Mesolecithal**: These eggs have a moderate amount of yolk. They are usually seen in organisms where the embryo requires a fair amount of nutrients during development.
- **Telolecithal**: These eggs have a large amount of yolk that is unevenly distributed, often concentrated at one end of the egg. This type is common in organisms that have a longer development period.
- **Centrolecithal**: These eggs have yolk concentrated in the center of the egg, surrounded by a thin layer of cytoplasm. This type is typically found in some arthropods.

2. **Identify the Egg Type for the Given Organisms**:
- Butterflies, moths, honey bees, and beetles are all insects.
- Insects generally lay eggs that are classified as microlecithal due to their small size and low yolk content.

3. **Evaluate Each Option**:
- **(a) Microlecithal**: Correct, as these insects lay eggs with minimal yolk.
- **(b) Mesolecithal**: Incorrect, as these eggs have a moderate amount of yolk, which is not characteristic of the mentioned insects.
- **(c) Telolecithal**: Incorrect, as these eggs have a large amount of yolk and uneven distribution, which does not apply here.
- **(d) Centrolecithal**: Incorrect, as these eggs have yolk concentrated at the center, which is not the case for butterflies, moths, honey bees, and beetles.

4. **Conclusion**:
- Based on the analysis, the correct answer is **(a) Microlecithal**.

### Final Answer:
**(a) Microlecithal**
