There are three ocelli or ocelli between the two capitals. Each ocellus is composed of a lens and a cluster of photosensitive cells. Each lens is thick, clear and made up of cuticles. Sensory cells contain pigments. It contains coniagen cells, retinular cells, rhabdomes, pigmented cells and neurons. Grasshoppers sense changes in light intensity with the ocellus. Many people think that a single reflection is formed through this. Dr. Siddiq Publications
