Hello, I'm an expert in entomology, the study of insects, and I can provide you with detailed information about the eyes of butterflies.

Butterflies have a unique visual system. They possess a pair of compound eyes, which are large, dome-shaped, and prominent structures located on either side of their head. These compound eyes are made up of thousands of individual units called ommatidia, each functioning as an independent light-detecting unit. This gives butterflies a wide field of view and the ability to detect movement.

In addition to their compound eyes, butterflies also have three simple eyes, known as ocelli. These are located on the top of the head, between the compound eyes. The ocelli are not used for detailed vision but help in detecting light intensity and direction, which can assist in navigation and coordinating flight movements.

So, to summarize, a butterfly has a total of five eyes: two compound eyes and three ocelli.
