It looks as though (sorry for the pun) bees have 2 eyes – the large ones that we see. These are the bee’s compound eyes that consist of many tiny lenses that piece together patterns that the bee sees, enabling it to recognize types of plants and other bees. However, the bee also has 3 additional eyes on the top of its head. These are called simple, or ocelli eyes. These eyes do not see patterns, but can see light. Or more importantly, these eyes see changes in light, which can alert the bee to predators flying overhead. If you look carefully, you can see one of these small ocelli eyes in the top photo; look at the large eye on your left, then look across the top of the bee’s forehead that has black coloring. At the inner tip of that, almost in the center of the forehead, you will see the leftmost oceilli eye as a very small dot. See it? Well done! You can also just barely see it in the second photo.*
