2. What is the related topics?Arthropod evolution, visual neuroscience, biomimicry, optical engineering, insect ecology, polarized light vision
3. Why do some insects have a 360‑degree view?Their ommatidia are arranged so they can see almost all around them, helping them spot predators or prey from any direction.
4. How do insects see ultraviolet light?Some insects have ommatidia that can detect UV light, letting them see patterns on flowers that humans cannot see.

Compound Eye: A visual organ composed of many individual ommatidia, offering a wide field of view and superior motion detection capabilities.
Ommatidium: The basic structural and functional unit of a compound eye, comprising a lens, photoreceptors, and associated cells.
Rhabdom: The light-sensitive part within an ommatidium, formed by the microvilli of photoreceptor cells.
Apposition Eye: A type of compound eye where ommatidia function independently in bright light, with minimal light leakage between them.
