Insect: Which structure forms the images we see?

• A. Antennae
• B. Wings
• C. Compound eye
• D. Mandibles

Answer: (C)

Images seen by insects are formed by the compound eye, which is made up of many tiny units called ommatidia. Each ommatidium has its own lens and photoreceptor cells that sample light from a small portion of the visual field. The brain combines input from all ommatidia to create the overall image, giving insects a wide field of view and good motion detection, though detail resolution is often lower than in vertebrate eyes. Antennae detect smells and touch, wings are for flight, and mandibles are mouthparts for feeding or manipulating objects. Some insects also have simple eyes called ocelli that sense light intensity, but they don’t form detailed images like the compound eye does.
