Although bed bugs love feeding on human blood they do not have eyes that see like human beings. These parasitic creatures have what is called a compound eye structure. It’s thought that they do not see in color, that they visualize in black and white.

A bed bugs eye is made up of hundreds of eye lenses called sides that fit collectively in a hexagon structure. A simple way to image what this insects eye looks like is to think of a bee honey comb in a conical shape and not flat. It’s like a soccer ball, however on a smaller, more complicated level. The individual facets consist of lenses, one on the surface and one on the inside. The bed bugs dual lens eye structure allows it to see in three-D. All of these sides fitted collectively assemble the parasites eye. These sides are related to tubes that focus light down a central construction called the rhabdome. The rhabdome is light sensitive and directs the data through an optic nerve to the bugs brain.

Each particular person facet within the bed bugs eye sends a different image to it’s brain. When all these photos are processed and put together a mosaic is created. This 3-D mosaic is how the bed bug can see it’s human host. It isn’t known if, because the bed bug moves, the picture it sees updates on an entire or takes micro-seconds for each lens to replace the visual information. If this parasitic insect’s vision updates lens by lens then it would see a constantly updating picture. This view would kind of be like looking by means of a kaleidoscope with three-D glasses on.

Bed bugs come out at evening or in the dark to feed on their human hosts for a couple of reasons. One reason is because at night, when you find yourself in your bed sleeping, you won’t really feel them crawling on you and biting you. Another reason might be that these blood suckers have light sensitive eyes that enable them to see better in the dark. These compound eyes also can pick up a heat signature of the human body. This is why the most importantity of bed bug bites occur on the center of mass part of your body. Your heat signature is warmer in your torso, legs, and arms than it is in your fingers and toes.

People could have color vision that updates consistently the place as bed bugs compound eyes see in black and white. Their eyes additionally don’t continually replace the complete image directly, but they’ll see very well to do the job they are greatest at. That job is to find a human host in which to feed off of their blood.
