Simple eye in invertebrates. A simple eye (sometimes called a pigment pit) refers to a type of eye form or optical arrangement that contains a single lens. A simple eye is so called in distinction from a multi-lensed compound eye, and is not necessarily at all simple in the usual sense of the word. The eyes of humans and large animals, and camera lenses are classed as simple because in both cases a single lens collects and focuses light onto the retina or film.
Carpenter bees are a very calm type of bee. While they are very damaging because they burrow into homes, they will tend not to harm humans. Luckily, male carpenter bees do not sting because they are not equipped with a stinger.ou would need to do something extreme like grab it in your hand or poke it in order for it to sting. Otherwise, it will not sting. Females also do not die when they sting you as would other bees. If you are stung by a female carpenter bee, you may want to put ice on the sting to ease the pain.
