Human Body Louse
Closely related to the head louse but lives in clothing rather than on hair. It is the vector for epidemic typhus, trench fever, and relapsing fever.
Did You Know?
Body lice are believed to have evolved from head lice when humans first began wearing clothing roughly 70,000 to 170,000 years ago.
Slender Pigeon Louse
A long slender louse found between the barbs of wing and tail feathers of pigeons and doves. It is one of the most studied louse-host systems in biology.
Did You Know?
This louse has become a model organism for studying coevolution, as its evolutionary tree closely mirrors that of its pigeon host species.
