Naked Human Louse (Head, Body, or Pubic Louse remnant)
Phthiraptera (likely Pediculus humanus or Pthirus pubis)
- Order & Family
- Order: Psocodea (formerly Phthiraptera), Family: Pediculidae or Pthiridae
- Size
- 1mm to 3mm
Natural Habitat
Exclusively on human hosts; specifically the hair of the scalp (head lice), clothing fibers (body lice), or coarse body hair (pubic lice).
Diet & Feeding
Obligate hematophages; they feed exclusively on human blood several times a day.
Behavior Patterns
They are wingless, crawling insects that cannot jump or fly. They attach their eggs (nits) to hair shafts or clothing seams and glue them in place. They die within 24-48 hours if separated from a human host.
Risks & Benefits
Risks: Can cause intense itching, allergic reactions to saliva, and secondary skin infections from scratching. Body lice specifically are vectors for diseases like typhus. Benefits: None to the ecosystem or host; they are strictly parasitic.
