Phthirus pubis, commonly known as pubic lice or crabs, is a parasitic insect that infests the pubic hair region of humans. Here are some characteristics of Phthirus pubis:

1. Size: Adult pubic lice are small, measuring about 1.1 to 1.8 millimeters in length. They are visible to the naked eye.

2. Shape: Pubic lice have a crab-like appearance, with a broad, rounded body and six legs. Their front legs are larger and adapted for gripping onto hair.

3. Color: They are usually grayish-white or yellowish-gray in color, which helps them blend in with the hair.

4. Habitat: Pubic lice primarily infest the pubic hair, but they can also be found in other areas with coarse hair, such as the armpits, eyebrows, and eyelashes. They require human blood to survive.

5. Transmission: Pubic lice are usually transmitted through sexual contact, but they can also spread through close personal contact, sharing infested clothing or bedding, or using infested towels or washcloths.

6. Life cycle: The life cycle of pubic lice consists of three stages: egg (also known as a nit), nymph, and adult. The eggs are laid on hair shafts and hatch within 6 to 10 days. The nymphs mature into adults within 2 to 3 weeks.

7. Symptoms: Infestation with pubic lice can cause intense itching in the affected area. Other symptoms may include the presence of lice or nits in the hair, small red or blue spots on the skin, and sometimes a bluish-gray coloration of the skin.

8. Treatment: Pubic lice can be treated with over-the-counter or prescription medications that kill the lice and their eggs. It is also important to wash or dry-clean infested clothing, bedding, and towels to prevent reinfestation.

9. Prevention: Practicing safe sex, avoiding sharing personal items, and maintaining good personal hygiene can help prevent the spread of pubic lice. Regularly checking for lice or nits in the pubic hair can also help detect an infestation early.
