Bed Bugs - How Do They See?

Although bed bugs love feeding on human blood they don't have eyes that see like human beings. These parasitic animals have what is referred to as a compound eye structure. It's believed that they don't see in color, they visualize in white and black.
A mattress bugs eye is composed of countless eye lenses known as facets that fit together in a hexagon construction. A simple way to picture what this insects eye resembles is to think of a bee honey in a conical form rather than level. The individual facets include two lenses, one on the outside and one on the interior. The bed bugs dual lens eye structure lets it see in 3-D. Every one these features fitted collectively construct the parasites eye. These aspects are connected to tubes that concentrate light down a fundamental structure known as the rhabdome. The rhabdome is light sensitive and transmits the info through an optic nerve into the bugs brain.
Each individual facet in the bed bugs eye sends another picture to it's mind. When these images are processed and gather a mosaic is created. This 3-D mosaic is how the mattress bug can see it is human host. It is not known if, since the bed bug moves, the picture it sees updates onto a whole or takes micro-seconds for every lens to upgrade the visual info. When this parasitic insect's eyesight updates lens by lens then it might see a continuously updating picture.
Bed bugs come out at night or at the dark to feed their individual hosts for a few reasons. These chemical eyes can also pick up a heat touch of the human body. That is the reason the majority of bed bug bites occur on the center of mass component of your body. Your heat signature is warmer in your chest, legs, and arms than it's on your fingers and feet.
Humans may have color vision that updates constantly in which bed bugs compound eyes see in white and black. Their eyes also do not always update the full picture at once, but they can see quite well to perform the job they're best at. That job is to locate a human host in which to feed from their blood.
