This is perceived in bright light, when pigment cells in the dioptrical and sensory regions spread and completely separate the ommatidia from each other, so that the angle of vision of an ommatidium is only 1 degree and light rays coming directly from the front can only enter the ommatidium, whereas the light rays coming at an angle are absorbed by the pigment before they can reach rhabdomes. The image formed in brain is a mosaic of several dots, each one of which is formed by an ommatidium.

Apposition Image in Cockroach
Apposition image is a type of compound eye found in insects, including cockroaches. In this type of eye, each facet of the eye (known as an ommatidium) forms a separate image, which is then combined in the brain to create a larger image. Cockroaches have around 2,000 ommatidia in each eye.
Bright Light
Apposition image is formed when there is bright light. This is because the bright light allows the cockroach to see more clearly, and the apposition image allows it to detect movement and navigate its environment effectively.
Dim Light and Total Darkness
In dim light or total darkness, a different type of compound eye called a superposition eye is used. In this type of eye, the images from each ommatidium overlap to create a larger image with better sensitivity in low light conditions.
Conclusion
In conclusion, apposition image in cockroach is formed when there is bright light. This type of compound eye allows the cockroach to see clearly and navigate its environment effectively. In dim light or total darkness, a different type of compound eye called a superposition eye is used.
