Bed Bugs have five different stages. With each stage the bed bugs become browner or brunt orange. When the female bed bugs lay their eggs it is a milky white color being no bigger then a pin head. The newly hatched nymphs are translucent, lighter in color becoming darker and darker as the proceed to the next stage. When the bedbug nymphs feed on blood, the back of the bed bug will appear as dark red or black.
Bed Bug eggs are about 1mm in size, about the size of a poppy seed. The adult are about 1/4 inch in length. The size of bedbugs are compared to letils or appleseeds. Bed Bugs have very flattened bodies from top to bottom and are oval shaped. When engorged with blood the back of the bedbug is no longer flatten. Bed Bugs in the maturity can feed on a human within 5-15 minutes causing their bodies to fill up to 3 times its normal size.
Bed Bugs have a large, around abdomen, long 4- segmented antennae, and a small prothorax that flares to the sides. Their mouth is a short, 3- segmented proboscis that is held below the body when at rest. The human bed bug is distinguished from other species by the antennae, where the last segment is shorter than the segment before it, the fringe of hairs along the sides of the pronutum are very short, and the front of the pronotum is deeply concave.
There are five stages of a bed bug. The newly hatched bed bugs need five significant blood feeding to fully mature. They will molt in between feedings by shedding their exoskeleton. Bed bugs have an elongated beak that is used to pierce the host while feeding.
