Which one of the following best describes the ectoparasite that causes pediculosis pubis?
Figure 1. Adult Crab Louse (Phthirus pubis)
The adult crab louse (Phthirus pubis) is 1 to 2 mm in length and has 6 legs; when viewed through a magnifying glass, they appear tan to grayish-white in color. The two front legs stand out as much larger and look like the pincer claws of a crab. Some have described the pubic louse as resembling a miniature crab, hence the name crabs.

Figure 2. Life Cycle of Crab Louse
Adult female insects lay eggs (nits) that adhere to the hair-skin junction. The nits hatch in approximately 6 to 10 days and mature from the nymph stage to adult stage within 10 days.
