This Praying Mantis has three simple eyes in the center of its face, and two large, compound eyes. What are the two black dots on the compound eyes?
The black dots are pseudo-pupils. This is an illusion that is often seen in animals with compound eyes. The dark spot appears to be pointed directly towards the observer (or camera). An easy way to check this is to have several people look at the eyes. Each will see the "pupils" looking at them, all at the same time.
