Pubic louse

Human pubic hair and occasionally other coarse body hair such as eyelashes, eyebrows, and armpits.

Exclusively human blood, feeding multiple times daily.

Spends its entire life cycle on a human host, clinging tightly to coarse hair shafts and transmitting primarily through intimate physical contact.

Causes severe itching, skin irritation, and secondary infections from scratching; provides no ecological benefit to humans.
