it is called a compound
The insect with approximately 12,000 eyes is the compound-eyed dragonfly. Dragonflies possess large compound eyes made up of thousands of individual lenses, allowing them to have a wide field of vision and detect movement effectively. This remarkable adaptation aids in their hunting and navigation abilities.
Dragonflies have compound eyes that are made up of thousands of tiny lenses, called ommatidia. Each compound eye can contain anywhere from 15,000 to 30,000 ommatidia, allowing them to have a wide field of vision and detect movement very effectively. Therefore, while they have two eyes, each eye consists of thousands of lenses.
A fly has compound eyes which are made up of thousands of individual lenses. Each compound eye is made up of approximately 4,000 individual lenses, giving the fly a total of around 8,000 lenses in two eyes.
Flies have compound eyes made up of thousands of individual lenses called ommatidia. These lenses each capture a small portion of the visual field, which is then combined to create a mosaic image. Flies can detect motion very quickly with their compound eyes, helping them navigate and evade predators.
A housefly has compound eyes, which are made up of thousands of individual lenses called ommatidia. Each ommatidium acts as a separate visual unit, contributing to the fly's overall compound eye structure.
The short answer is: nothing.The slightly longer answer is: Insect eyes are completely different from our own eyes. Ours is rather like a camera, with one lens and a retina (film) at the back. Insects have compound eyes with thousands of lenses, each with their own tiny retina. Each lens points in a slightly different direction and covers a very narrow field of view. Because of this what the insect sees is rather like a mosaic. Overall, an insect's eye is not as good as ours at seeing fine detail, but they are very sensitive to movement in the visual field.If you see a photograph of a young bee you may see hairs between the lenses, but these don't affect the bee's vision.
they have two eyes. These are called facet eyes. all flies have more then two eyes, most have two compound eyes and three simple ones Flies have two compound eyes. Compound eyes can consist of thousands of photoreceptor units (ommatidia), or individual eye units that focus sight in different directions.
they can see in many directions because their eyes are in different positions than fixed like our eyes. Also some insects have many lenses to their eyes like a bee, wasp or fly.
Butterflies typically have two large compound eyes, with each eye made up of thousands of tiny lenses called ommatidia. They also have two simple eyes, called ocelli, which can detect light and dark but are not as complex as their compound eyes.
A fly is an insect, mainly because it has wings and only 2 eyes (but many lenses).A fly has soft skin and no skeleton (like a worm), while arachnids have an external skeleton.I hope this answer has been helpful.
dragonfly
they have over 8000 eyes
