What do insect eyes look like?
We found a small, flying bug stuck to a leaf covered in honeydew. Using the sticky side of a cover slip, we removed the bug and mounted it on a slide. Viewing the slide with a cell phone, we zoomed in on the head of the insect and adjusted the focus on the Foldscope until the eyes became clear.

The left eye of a flying insect Looking the eyes of this bug, we saw that they stuck out from the sides of the head, giving the bug an unobstructed view of whatever lay ahead. They were round on the front, like our eyes, but on the back they were flat. The way they were attached to the head also made it seem as if they were stuck in that position, which means the bug would have to turn its entire head or body to see anything other than what is in front of it. The eyes appeared to have many raised bumps or segments, which we concluded to be lenses. Does having multiple lenses mean that the bug sees multiple images, or does it see one complete image as a human would? If the Foldscope had multiple lenses like an insect, would it allow us to see better images, or would it be too hard for us to see?
