Male moths recognize females of their species by sensing chemical signals called pheromones. This is an example of

Options

A. gamete isolation.
B. habitat isolation.
C. behavioral isolation.
D. mechanical isolation.

Explanation

To solve the question regarding how male moths recognize females of their species through pheromones, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Pheromones**:
- Pheromones are chemical signals released by an individual that can affect the behavior or physiology of another individual of the same species. In this case, female moths release pheromones to attract male moths.

2. **Recognition Process**:
- Male moths have specialized receptors that detect these pheromones in the environment. When a male moth senses the pheromones, it can identify the presence of a female moth of the same species.

3. **Behavioral Isolation**:
- This method of recognizing females through chemical signals is an example of behavioral isolation. Behavioral isolation occurs when different species have different mating behaviors or signals that prevent them from interbreeding.

4. **Importance in Evolution**:
- Behavioral isolation is significant in the process of evolution as it helps maintain species boundaries. It ensures that mating occurs between individuals of the same species, which is crucial for the continuation of specific genetic traits.

### Final Answer:
The recognition of female moths by male moths through the sensing of pheromones is an example of **behavioral isolation**.
