All of the following are sensory structure of arthropods, except

Options

A. Ocelli
B. Statocysts
C. Antennae
D. Malpighian tubules

Explanation

To solve the question "All of the following are sensory structures of arthropods, except," we will analyze each of the options provided:

1. **Ocelli**:
- Ocelli are simple eyes found in many arthropods. They are responsible for detecting light and dark, thus serving a sensory function. Therefore, ocelli are indeed a sensory structure.

2. **Statocysts**:
- Statocysts are specialized sensory organs that help in maintaining balance and orientation in arthropods. They detect changes in position and are crucial for the animal's spatial awareness. Hence, statocysts are also sensory structures.

3. **Antennae**:
- Antennae are appendages found on the heads of arthropods. They are primarily involved in sensing the environment, including touch, taste, and smell. Therefore, antennae are classified as sensory organs.

4. **Malpighian Tubules**:
- Malpighian tubules are excretory structures in arthropods. They play a role in osmoregulation and the removal of waste products from the body. They do not have a sensory function.

After analyzing all the options, we conclude that the structure that is not a sensory organ is:

**Answer: D) Malpighian Tubules**
